If you think about it that can't be it, mainly because the Mangekyou Sharingan is very rare, so they wouldn't plan on an Uchiha with it appearing.
It's one of the strongest powers on the planet, surely they would know that (for proof of the Mangekyou's strength i refer you to....the episode when Itachi and Kisame turn up and Itachi totally whupps Kurenai and Kakashi, i don't know numbers....
), this means not many people, if anyone could stand up to it's full might.
Besides when Kakashi says "Only one with the Sharingan can stand up to him now," he's right, but he doesn't know that it needs to be at least a full blood Sharingan, if not another Mangekyou.
FYI: The anime got it wrong, the Mangekyou Sharingan isn't just another Doujutsu, it actually looks different to the normal level 3 Sharingan and is another level of ability
