Well... pretty much as the title says -- is it possible to take a stock sprocket and drill some holes or do whatever so it could fit on a MM adaptor?

I've done it.
Measure it real good, so you get it centered good, so it will not wobble/hop.
I'll try to get a picture of it tonight.

it's possible. just make sure you get the holes centered properly. i drilled and countersunk a steel, 30t moped sprocket to fit one.

i also modified a MM sprocket to fit a moped hub that's got 6 mounting holes cast into it.

i had to bore out the center hole of the sprocket and use some forgotten high school geometry to center all the holes but it works fine.
