I doubt it, being that his goal is to destroy the hidden leaf and their goal is to protect it. He's a missing-nin, meaning that he's wanted by his village. The hidden leaf village has also sent a division of Anbu, the Root division, to kill Sasuke before. And, while his brother was a member of Anbu, they required him to spy on his family and eventually kill all them except Sasuke. So to make a long story short, naruto and sasuke becoming lovers is a much more likely plot twist than Sasuke joining anbu at this point.
