Like how Orochimaru summons all sorts of snakes, Jiraiya summons frog guards and Tsunade summons katsuyu for offensive and defensive purposes.

Besides, MS obito is already ridiculously strong by himself. Itachi was implied to be equivalent to a Sannin by himself, and EMS sasuke can easily be considered a Sannin's equal or more.

So basically we have 2 uchiha who can be considered Sannin level or above and Obito. I don't see the Sannin winning this in any way.
