Rasengan is already in the game, about the way you described it.
I wanted to have Chidori the same way, but sadly it was already in the specialties before I realized that.
Medical is a standard issue that can be learned anywhere, though the strength, yes, is currently not implemented.
I am not inclined to add more stacked up power jutsus to a char that "pays once".
Sorry should have been more clear. Pay for each lesson

As for jutsu, can't you just take out Raikiri,Raikiri Nirentotsu and Raikiri Issen. You need 16 for raikiri, 18 for nirentotsu and 23 for Issen. I doubt that anyone who's not a sitter gets that far in a specialty. Or you could replace the lower ones with things like sasuke's lightning thing he does with his hands or puts on his weapons to do extra damage..?
