Turns into? Hell, he already IS a jesus-ninja. ;)

I could always switch him back to his original ability, which was that he can draw on the ambient force energy brought to the area by the presence of a force user in order to increase his own physical stats. He doesn't drain anything away from the force user in question, but the more force users there are/the more powerful a force user is, the stronger/faster/tougher he can get.
