Nah, it wouldn't balance it just smooth it. Different density between the epoxy and rotor so for that to work you would have to grind away all the epoxy. Easiest way to balance is to put it in extremely smooth bearings and spin it. Where it stops, lightly sand the bottom a bit. Spin it again and see what happens. Do that until the rotor doesn't stop in the same place every time and your done. There are more precise ways but nothing without a sophisticated machine that I am aware of.
