No. All of the pc boards would need to be redone.

The MOTM-800 uses 1/8" spacesr.

I think they are OK as well.

I don't think so, but what I can do is change the pcb slightly so the voltage 
swing is much less across the pot to minimize the drift. The Coarse/Fine pots 
are ratiometric, which reduces drift anyway.

24x are all plastic. I tried those on the original MOTM modules. Awful!!!
