That's where the BasicX becomes a star. It does everything a stamp can do
for the same price but it has the added bonus of ADC and 2 x real PWM
Check out the comparison.

Rather then make lots of fudgy circuits to patch your PWM it would be easier
to change the stamp to a basicX, You will likely run out of program space
and ram later anyway.
