You know it is rocket surgery when you have to stick your hand up in the nozzle to check the orifices....

Or is I orifi?
Oh yes, you can put an even smaller filter on the 6.2L and probably get away with it. But more filter area is better than less. Just ask AFe, AIRAID, Volant, etc.
I have to chime in here. The overall size of the filter shouldn't affect oil flow whether you increase the size or not. The AMSOIL EA oil filters use a "nanofiber" synthetic media that filters to 97.3% efficiency for particles down to 20 microns in size where the Ford racing filters use a silicone media that filters at about 80% efficiency down to 20 microns. For better filtration, there is no better choice than the AMSOIL EA oil filters. That is while still providing more than adequate flow through the filter so as not to starve the engine.
That being said, there is also the option of installing an external bypass filtration system. I broached the subject last year sometime, but haven't been able to get back around to developing a mount that would work with the Raptor and be safely mounted out of the way for those that go offroad a lot. That mount development would be very tricky. More about that can be found HERE. I am planning on finally ordering a bypass system to try and get started on designing a mount that will work and be offroad friendly for the Raptor.
But, all that being said. The overall size of the filter itself, whether talking about the AMSOIL filter or the Ford racing filter, is not as important for flow as you might think. Because of the synthetic filter medias being used, the filtration is better and they do not restrict flow as much as say a larger filter full of basic paper filter media.

Chris, what's your price on those Amsoil filters, please?
I got mine off of ebay. They were actually bought from Roush Yates which sold them on ebay. They were 14.96 plus 6.95 shipping. I thought that was a little high but didn't care. Don't change them often enough to really cost me to death. My oil changes come due 3 times a year.
Oil Filter model number is CM-6731-FL820. Its a really nice filter. When you hold it, it feels like a really strong nice filter. Insides look real nice too. Its the only filter I run on my Raptor.

And for all those pencil ***** out there, throw on a glove after you pull it off and you get a home made "fleshlight" with (insert oil name here) for lube. 
BTW, Us old ***** remember when it wasn't about numbers on an oil filter to match em up. You stuck your index finger in the hole to measure the thread size and matched gaskets by mating filters.

Oh yes, done that many times. I run a filter on my 1997 Buell that was selected in that manner.

I have looked at some spec books and found filters that are longer with same thread, but either they did not have the drain back valve, or the filter was not as fine a micron rating.

There is definitely not a Motorcraft filter with a larger capacity to replace the FL-820S. I can't confirm that for a Ford Racing filter, but I don't think there's an option there either.
I have no evidence to prove that the AMSOIL EA filters are too small and unless someone has done a flow rate test with the bypass taken out of the equation, we'll never know for sure. I agree that the AMSOIL EA filter media has the ability to capture more particles than a Motorcraft or Ford Racing filter, but I'm not sure I believe that the entire filter assembly as a whole will capture more in real world use... especially after a few thousand miles and dirty oil. The AMSOIL EA efficiency is 93.7% @ 20 microns, meaning that the filter element will capture 93.7% of particles that are 20 microns or larger; similar for the Ford Racing filter, but only at 80% efficiency. My fear with the AMSOIL filter is that because of it's small size and higher filtration ability, the filter will clog faster and create an increasing restriction as time goes on, making it more likely to activate the bypass, in which scenario it won't be filtering anything. I've seen a few comparison studies done where people have cut open various filters after using them and compare how much they've captured; yes the AMSOIL EA filters typically win this comparison, but how do you know the bypass never activated during that cycle? I'd rather have 80% filtration all the time than 93.7% filtration some of the time.
Again, I have no way to prove any of this, but it's just too puny for me and I'll stick with the Motorcraft/FR filters.
Also, does the AMSOIL EA filter use a silicone ADBV and is the bypass located in the cone or the base of the filter?

They retail for $17.75, but the wholesale cost provided by myself or through an account with Amsoil is $13.15 before shipping and sales tax. Amsoil has to charge state sales tax according to the rates in the state of delivery because they can show an active presence in every state.
As far as I know, the ADBV is indeed silicone instead of nitrile based. That being said. I have tested and I have had customers and my dealers test the AMSOIL filters for extremely extended intervals without issues with them going into bypass. First, I misspoke on the efficiency, it is actually 98.7% at 20 microns, but they were upgraded sometime in the past couple of years. That being said, the testing I have seen with very long intervals has shown that the filters continue to filter with plenty of flow, without going into bypass for much longer than folks would expect. The last oil analysis sample I was privy to was on a 2008 Duramax diesel that had an engine flush done during installation of the first oil change and then the second oil change was done within 3K miles to further clean things out of the engine. Once done, the owner used UOA every 7K miles to determine his intervals and the last report I saw from him was at 34K miles on one oil and filter change when the lab said to continue to run it and test in another 7K miles WITHOUT a filter change.
You see, it is not JUST about the filter being used either. The higher quality oils made from Group 4 base stocks will also help to eliminate the build up of contaminants in the oil itself. This is why AMSOIL gaurantees their oil for their recommended intervals when used with their oil filter. Using the quality oil with the better filter greatly reduces the chance of clogging the filter as well.
THAT being said. I have actually never seen or even heard of anyone clogging the AMSOIL filters or having issues with them going into bypass due to holding too much trash. I have been running their filters on everything I own since early 2007 in some extreme conditions and have never had problems with oil pressure, flow, lack of filtration or anything even remotely associated with any of that.
One last thing, when ordering through a dealer like myself, or allowing a dealer like myself to get someone signed up for a Preferred Customer account, AMSOIL oil and filters cease being more expensive than the others for the most part as well.
