There are moves in ballet that focus entirely on ballancing on one leg for an extended period of time.

I think it is possible, but he would have to compensate for things like running - so rather than running, he could do sliding or rolling moves, possibly even handstands and flips. He should really be using his crutch as a weapon as well. It does provide a slight weakness, as people who fight him will most likely notice that he favours the other leg, but if he keeps on the move enough using acrobatics focused on rolling more than landing on his feet and uses the crutch as a weapon in conjunction with his actual weapon, it would be harder to take advantage of it.
