A toss up fight in my opinion, Cotto seemed badly drained during his last couple bouts as a jrweleter so Hatton outworking him would surely be a possibility.
i think hatton is too small at 147 and cotto weight drained at 140, but they could fight at a catchweight and it shouldn't affect either too badly and it would be an amazing fight and i could see it maybe happening in a couple of fights time.
