That wasn't one of the options I was suggesting... as I've said, and so has
Keith, if you don't want to alter the signal path at all, then motorising
the pot is the only realistic option- I assumed you wouldn't want to
replace the pot, but if you do, a motorised one would be the sensible way
forward to avoid re-inventing the wheel.

For me, I'd be more likely to alter the signal path while fitting a motor
(probably by nudging a trimmer on the board) than I would by adding some
electronics, but YMSMV (Your Mechanical Skills May Vary) :-)

So, as I said before, these are your options, if your choice is the
mechanical one, Keith's covered it well.  None of them involve replacing
the amp, all involve adding something to it, all but the motor option will
definitely have _some_ effect on the signal, whether positive, negative or
inaudible.
