Aion Graviton: 4PDT to switch HM2 Mid pot in and out

[ElCapitan]

Howdy all, I'm going to build an Aion Graviton, which is an HM2 clone.   There is a set of traces if you wish to add a mid pot, but you have to cut the "2" trace so that it isn't linked to the stock high pot.   However the build doc warns that this sort of changes the character of the pedal.   My experience with the stock HM2 is that there's a bacon sizzle on top I'm not overly fond of.  The Left Hand Wrath, which has the mid pot, does address this, and it still does the Swedish Death metal thing.   So, I'm inclined to build it with the mid pot, but just in case it alters the tone too much, I want to have an option to put the pot on a switch (assuming I want both, otherwise I'll just jumper them).   here's my idea for the wiring.  Thoughts?

Kinda hard to tell without the schematic, so I copied that part from the schematic:
