A really interesting plot twist could be the appearance of the Sage of Six Paths in the SAO world. He could be a mysterious figure who gives quests to the players. Or perhaps the SAO world is actually a creation of an ancient ninja jutsu gone wrong. Naruto and his friends from the Naruto universe, along with the SAO characters, would then have to find a way to fix this jutsu - created world. This would involve a lot of exploration, both of the game world and the secrets of ninja magic.
Well, a great plot twist might be if the Sharingan had a unique effect in the SAO world. For example, it could allow the user to see hidden codes or glitches in the game. And what if some of the SAO bosses were actually jinchuriki - like beings? Naruto would have to use his knowledge of taming the nine - tails to deal with them. Also, if Asuna had some sort of hidden ninja bloodline ability that gets awakened when she meets Naruto, that would be a really cool twist.
