i don't think so this is one of those situations where naruto kind of has to lose.

you think about it sasuke can't go back. he would be put under constant guard. and they would try to put a powerful seal on him to supress the cs lvl 2.

look at it this way, kimimaro who was a advanced blood line with cs lvl 2 was so powerful that gaara couldn't kill him, he was sick to if he was healthy rock lee and gaara would be dead.

so sasuke has a huge advantage over naruto even with naruto kyuubi.

this kind of situation requires someone of either kage tsunade or sennin, jiraiya to interfere which won't happen.
