Understood on the modifications, I have modified plenty of vintage amps myself in the same way. (always reversible)
I've posted an M12 schematic in the DOCs page. regarding more gain, you could adjust the gain of the paraphase phase inverter. assuming the supply would allow for it. You might take measurements of the supply voltage there, do some calculations and find out.
regarding tone shaping, I would mess with the values of the tone stack C6 and C3. Currently they should be .002uf and .01uf first try dropping c6 to .001uf and see if that solves it.
if that didn't quite do it you could try more values that you would find in a fender. c6=500pf C3 = .005uf
