Besides, I've always had a theory that attaing the power of senjutsu was one of the reasons for Orochimaru's desire to take over Sasuke's body. Since CS is basically senjutsu, and Sasuke proved to be compatible for it, it means that his body is potentially suitable for mastering senjutsu, the task Orochimaru failed to do exacly because he didn't possess a body strong enough.
