Now I donīt know how exactly one would realise this wiring whise but the first thought in my mind was as always an extravagant wiring plan (as I always tend to do):
Get a PG Blues set and a HS P90 (like the blue note) with screen for the middle. Now if you had a five way, you could have neck, neck + middle, middle, bridge + middle, bridge.
Now one of the PGs is always out of phase with the rest, I think its the neck.
Now if you were to wire the middle up to have a push pull swtich its phase or do series / parralel (probably the later) you would add another level of sound.
Finally include a switch that can put on only the two HBs alone for that classic in between Green sound.
That might give you a lot of options.
