Can either of you provide the schematic for the Morse Tone Pot mod for the HB to SC roll-off? I'm wondering if I can make it work as a Series to Parallel mod.

Colours are different for the Dimarzios --> B&W are to the pot and Red is hot.

There's no way to do series/parallel with a pot. You need a DPDT (6 lugs) for each p'up. But the "spin-a-split" works quite well. If you have a Silent Circuit handy, you can wire it up to ground the coil so as to get some noise reduction.

I had a similar scheme in my silo special for a while (but instead of being a blend pot for the two coils of a pickup it was a blend to bring the neck pickup in in series with the bridge) it's pretty neat.
