Hello Brian,
I am unable to create custom diagrams, and have looked through our archives and have not found one that fits your needs.
But hopefully I can explain how to modify the diagram to help you;
Here is our P-Rails with 1 volume PP, and one tone PP.
Reference this diagram to know how to wire up the P-Rails to the push pull pots.
See how there are 6 pins on each push pull, and those connections mirror each other coming of the pickups, so you can make the same connections on a second set of PushPull Volume and Tone pots.

Instead of the pickups Black wires coming off the PP to the 3 way switch, you would want to wire them to the input of their Volume pots Like a traditional Les Paul wiring, and then from the pot to your 3 way selector, then to your output.

Anybody willing/able to draw this up? I'm trying to hand draw it now, but I'm a novice at diagraming.
