From the description you gave of the bike in November, it sounds pretty trashed already. So, cutting it up to install a poorboy probably won't matter. It will probably cost more than repairing the stator. Quite a bit more work, also.
However...! It seems like you are getting ahead of yourself. You haven't got a clue what the problem actually is. It may just be one of the non stock lights or, more likely, a melted plug. Riding/charging/riding is a bad thing. A bad plug is more apt to damage the stator doing that.
Why ain't we ridin'?
