Somehow, I doubt Kabuto would appear, but all this are just assumptions.

What I do think would happen is that Kimmimaro would probably kick Naruto's ass (Naruto's form tend to be inconsistent), and Sasuke would finally come into the picture and kick kimmimaro's ass. However he would still follow the path towards the dark(sound)side unless one of the baddies accidentally spill out that Sasuke's body is going to be possessed.
