I don't think you can do all the splitting from that particular switch because you need one set of lugs to manage the bridge and the other set to manage the neck. That doesn't leave you spare lugs to manage connecting the coil series to ground or positive for the split.
Disappointing. What if I added a push pull volume pot the equation?
HH, volume pushpull, tone, 5 way rotary switch. With all that is it possible to get:
B HB, B S, B & N HB, N S, N HB.
A push pull added to the mix will get you there. You won't have the convenience of moving from B S >> B&N HB or going from B&N HB >> N S in one move, you'll have to hit both switches, but at least you will have access to all the sounds you want.
