Yes, it's possible to alleviate his mental condition, as well as eventually repair his face - in fact that had been done at least once, and probably more in publishing history. 

Unfortunately, Gotham is not the city where skeletons stay in the closet forever, so eventually SOMETHING is bound to happen that would push him back into one extreme or another.
