FYI. Each LP6 is 7.5amps total
6.5amps for the main light
1 amp for the IPT lighting
So 4x LP6 would be 30 amps. You never want to run an exact fuse size for the total amperage
If your lights call for 30 amps, you need a 35-40 amp circuit.
If the lights were say 29 amps... you'd still want a 35-40 amp circuit.
You gotta account for HEAT. That will cause the fuse to blow sooner if you're right at the edge of it's rating OR equal to it.
If you want them all on one switch you can always install 2 relay harnesses. We sell the Baja harnesses where 1 pair of LP6 are controlled from 1 harness. Since these are powered relay harnesses, pulling power from the battery you could use ANY switch to trigger them, as you don't need ANY amperage really to trigger the relay. you could wire 10 of these harnesses for 20 lights to a single switch on the SwitchPros and be fine (again power comes from the harness).
Sounds like you came up with a solution BUT if you ever wanted to put all 4 back on 1 switch, get 2 of these harnesses and wire the trigger wires to the switchpros
