It would be pretty hilarious of Kishimoto if he let those two go through further exams to properly become Chuunin, then Jonin and eventually Hokage.
But take Gaara, he was apointed Kazekage right away. I don't think he had any rank whatsoever.
I doubt Kishi wants to extend this manga to make the stage wise growth from genin to Jounin happen.
Taking a real world scenario, just make them Honourary Jounins. I doubt anyone would want to disagree.
Out of respect and love for Naruto.
Out of fear of Sasuke.
I am sure they would both hold the rank of Jounin when this is all done. Their is no way in bloody hell you can hold this 2 as eniting but elite jounin.
Even if Naruto is not the tactician with a team he is a leader like nobody else. He has a different type of "leading" but even Shikamaru feels like following him...
Sasuke ... You can't even argue about that...
