Depending on the circuit, that could be pretty tough! Most of the coupling caps in the signal path need to be swapped to convert from guitar use to bass use. Smaller value caps cut the unneeded lows out to tighten up a guitar sound. Bigger caps will let the bass thru, but often leave your guitar sounding muddy and undefined, or waste precious gain amplifying low frequencies that aren't even present in your guitar signal.
Needless to say, the changes needed for conversion will be different for every circuit. It would be possible for many circuits, but you might find yourself needing a microcontroller to run lots of solid-state relays to swap those caps in and out... or maybe some kind of double throw, MULTI-pole switch.
Any thoughts to being able to fine tune those lows for the guitarist who isn't utilizing those frequencies? I always assumed I could use a different pot for the tone control. Not sure it works that way... It's already great for bassists and tuned down doom/sludge guitarists. But for the standard tuned 6 string, I'd like them to have more control of the now wide open low end.
