Anything can be done as long theres enough money and patience... LOL
Like Naughty said the rear gen2 wheel can't fit on a stock gen1 swingarm, for that to work you would need to alter or make a new swingarm and change the wheel core to accept the gen1 drive. I don't know if you could use a full gen 2 swingarm, wheel and drive. I don't know the dimensions on those... but it might be doable if the offset angle is allowed by the U-joint and the frame doesn't get in the way. you would also to manufacture a bracket for the mono-shock and get it to fit behind the tank, maybe using the centerstand fixing points or similar, but thats only me talking without actually looking at it...
