Assuming Sasuke fought Naruto directly after he got EMS ( As he swore that he would kill Naruto, once he gets Itachi's eyes in the chapter where Naruto encounters Sasuke, Sakura and Kakashi ), Sasuke most likely would've come on Naruto's side directly and supported him in Fourth Shinobi War. Probably, the final Naruto vs Sasuke ( And Sasuke's revolution wouldn't happen ).

Another thing, is I don't think Sasuke and Naruto would've gotten their Six Paths powers and Rinnegan.
