Alternative wiring is to wire the high pass filter so it's on all the time, then either use the push pull volume as a kill switch for the neck humbucker as you did or install a dual concentric pot so you have a volume for each humbucker.
That way you keep the coil tap.
Personally I'm not overly fussed about the high pass, although I think I'd wire it on than off and I keep meaning to remove the coil tap from the bridge humbucker as it's a sound I never use.
I like the single coil neck sound but that's it, even the middle setting with both coils isn't that great compared to something like a RG2820 which has the same inner two coils active on that position. ok body woods and pickups are completely different but still......
