Inspired by Mincer's efforts, I wired my HH Strat with a 5-way superswitch, two independent volumes and a single tone.
The superswitch gives:
P1 - bridge humbucker both coils
P2 - both humbuckers slug coils parallel
P3 - both humbuckers both coils in each
P4 - both humbuckers screw coils parallel
P5 - neck humbucker both coils
I can select an individual single coil in P2 or P4 by turning down the volume on the coil I dont want.
Mincer and I both went further and flipped the magnet and wiring connections in the neck pickup, making it RWRP relative to the bridge, so in P2 and P4 the coils are hum canceling.
Just a thought.
