The EP1111 switch is designed to work with two humbuckers and have the following selections (aka John Petrucci wiring):
#1 bridge humbucker
#2 bridge + neck inner coils in parallel
#3 neck humbucker
It is not designed to work with three pickups, even though there may be possibilities to make that work.
You could use that switch to control the outside humbuckers and use the push pull pot to add the middle pickup.
With one push-pull pot it is not possible to split all three humbuckers - you would need a push-pull pot that has nine pins (I only know of pots that have six).
Which pickup combinations are the most important for you? That would help to design a wiring schematic.
