Rich's AGJM-1 Build

You can, though grounding the pots themselves is harder on a temporary basis. If it were me, I'd go for 500k to start with, then if things were sounding too bright (which I doubt), then swap to a 250k for the tone first, then if still bright, then 250k for the volume after that. Or with the 500k pots in place, wiring a 470k ohm resistor across each pot (the two outer tags on the pots) with clips will simulate 250k pots without having to fit them first to see if the change is better or worse.

Sounds like a great plan. Really appreciate your input mate !
