Can you use your new-er style rotor with your original stator? Are the crank bearings the same?
IMO, I don't think it's worth the extra maintenance for that slight reduction of rotating mass for the sprocket. However, I believe Pur Pony offers a lightened output shaft sprocket, or heck go with a full chain conversion, it's cheap, lighter, and you can pick your ratios.
