Well, he would probably get a ridiculous power increase comparer to what we've seen of Double Kamui when Kakashi and Obito teamed up. As a wild guess, i would say he would warp objects up to 3,474.8 kilometres across. He's got to show his full power, and he's got to help take down Madara. I seriously don't believe anyone will break infinite Tsukiyomi, but i do know that the diameter of the moon is 3,474.8 Km. Why does that number sound familiar? (Yes, i know it's unlikely, But it would certainly stop people saying Hashirama can beat him)
