The issue would be the spline pattern on the sun gear shaft. Is it the same diameter, does it have the same number of spines, and is there enough spline available in front of the flex plate to fit the rotor on? I know the hole in the rotor is a 1" diameter, 10-spline hole.
What would prevent you from just sliding the rotor (with just a round hole) over the splined shaft, and attaching it to the flexplate with a few screws? Splines are expensive to machine.
Balance. Control that and you're golden. Get it off center by a little and...well...I don't know what would happen...but I BET that it wouldn't be good 8*)
Simply bore the center hole to be a very light press fit over the splined shaft. Warm up the rotor slightly up and slip it in place.
I like the idea of using the splines, because that will control the balance, and provide solid trap for all the radial forces driving the system. With the screws, you're depending on them for both radial and axial forces. Not that they can't be sized appropriately, I just don't think they'd be as dependable as the spline.
The cost of machining the spline will likely be greater than the cost of the rest of the rotor.
