How would this work out?

1: Master volume. Move this pot to the upper bout position where the pickup selector normally sits to ease the wiring for the rest.

2: Bridge tone w/ Q filter for EQ

3: Neck tone w/ normal tone cap, PP to select between 2 caps

4: Combined tone w/ caps as per neck tone.

5: 4 position rotary switch to select positions 2-5 of L6-S switching, skipping the series positions. This switch also selects which tone pots are active.
