Squier Venus Re-Wired w/ JB & S-1 Switch | Help Me Get Creative

[Huddy]

So I got this Squier Venus which is kind of an oddball guitar in itself. When I got it, it had a an EMG 81 in the bridge and and the original neck single coil that was just acting as a place holder since the toggle had been replaced with a tone control.

I now have the original "Hot AlNiCo" single coil, a JB , S-1 Volume Switch (4PDT), and 3-way Toggle to jack. I'm thinking I want to do something more than just Splitting the JB. Maybe split and out of phase so I could get 5 different tones. I'm trying to think of some magical way to short out one coil and somehow when you put the toggle on the neck it lifts the short so I can have a 6th tone for two single coils in phase with the S-1 "Down". I think there is a way it'd be done by going parallel instead of just sending one of the coils to ground.

Here's my ideal-ish setup:

S-1 "Up"
Toggle Down - Bridge full humbucker
Toggle Middle - Bridge full Humbucker w/ Neck Single Coil in Parallel
Toggle Up - Neck Single Coil

S-1 "Down"
Toggle Down - Bridge Split Humbucker
Toggle Middle - Bridge Split Humbucker w/ Neck Single Coil in Parallel Out Of Phase
**Toggle Up - Bridge Split Humbucker w/ Neck Single Coil in Parallel In Phase** This one is the tricky one

Thanks so much in advance!
