Assuming it does happen, I see it turning out rather different. Naruto's power levels aside, (and the first person to make some joke about 9000 gets a dirty look
) his attitude is different. The old Naruto might have been willing to abandon his teammates to their fates, but Team 8!Naruto would need a very good reason to leave Chouji to take on someone twice his size and experience.
With his improved strength, agility, deadliness and tactical foresight, they ought to breeze by the first two enemies iin short order, I think.
As for people coming along, I see all of Team 8 going along. This is the kind of mission that they're trained for, after all, and I don't think that Shino would be split up from the team this time around. If Shikamaru is still appointed to lead (despite his non-Chuunindom), and we add in Fire of Youth, 1st Class Rock Lee, and Shika's sidekick, I mean teammate, Chouji, you've got the initial team. Neji might join in as the Calvery, saving someone's bacon at the last minute. (Bonus points if it is Hinata, he's got some karma to work off)
