You'd think it's legal, but the GDC had a fun related answer last year. They declared that you couldn't remove the gearbox from a first legal window motor and adapt another FRC legal motor to it, because the gearbox was integral to the window lift motor and couldn't be modified. By that reasoning, pulling the stock motor off a PG71 and replacing it with a different FRC motor would also be illegal. But if you bought the standalone gearbox, it presumably would then be legal.
