Let's assume that the 1st is actually taken by surprise (even though, rationally thinking it should be a wooden clone and not the real thing, since he is already facing a dozen of enemies), if that person misses his vital spot, then it's the end. Hashirama's regeneration/healing jutsu would heal him from near death situations.
Someone like Shisui could have a chance there, since his jutsu is currently the sure thing and we know that he can use it with one eye.
Hashirama is basically a tank, no he is something far superior. To him it doesn't really matter how many opponents he faces, since his style is just boasting jutstu on extremely wide range. Almost, if not all Uchiha that attacked him, would need to use the Izanagi at the same time to survive, so it's not like they could use this strategy more than once and they still would have a really slim chance of wining.
