I seriously doubt it, cause Kishimoto has already stated the last battle will be between Naruto and Sasuke....
I think Kakashi will win but be unable to kill sasuke, in which sasuke will take advantage and beat Kakashi, or Madara will intervene, either protecting Sasuke or attacking Kakashi....
and then later on, I think Sasuke and Naruto will fight, Naruto will win but at that moment, Madara will step in, and take Naruto, who perhaps protects Sasuke, saying he's felt like he's his real brother, and THEN sasuke will understand, and they will both go up against most likely a ten tailed Madara..
