I don't know why not. I've done a bunch of regearing with ZZ/ZZSE gears on an MT. You might have to remanufacture the gears to mount them on the chassis. Likewise, you might want to remanufacture the gears for the motor pinion and axle. Experiment, have a good time with your project, show us what you've come up with.
My site includes a tutorial for regearing MTs, as well as a gear ratio calculator, if that might be helpful to you.
