Well, Naruto would have gotten his body taken. I don't know what his purpose would be, but he would not achieve the level to compete Orochimaru in few years like Sasuke. Sasuke had Sharingan to beat Orochimaru's technique - Naruto has no counter.
On the other hand, Jiraiya would probably make Sasuke even weaker. Jiraiya is too soft and does not want to train people. He would not give a damn about an emokid and go bang girls in clubs. And Sasuke would never go TSM - befriending Toads is not his one of his hobbies. BTW, He would have been dead by now, since Manda protected him in Deidara fight. Gamabunta isn't as long as Manda, so Sasuke would have get caught on blast.
Nope. Just no.
