Do you want to stick with a two knob layout like the '51?

If you go for a 3 knob option as volume, volume, tone you can do parallel/series/split switching on the DP120 with push/pulls on the two volumes, and have a tone push/pull to switch between normal tone control and bass cut or maybe use a Fender TBX style tone control. Lots of possibilities.

From what I've read, the DP120 is a little different internally to the original sidewinder coil layout in a Mudbucker, but has many of the same pros and cons sound-wise. Different sound, but more manageable resistance/load in conventional layouts.
