Hatton could beat the other belt holders handily enough I think Paulie, Bradley, Kotelnik would all succumb to pressure but some of the up and comers are more interesting.
Don't overrate Hatton. He'll be retired before the young guys are ready to step up to fight. He could lose to any of the tops guys at 135 or 140 but he would be the favorite to win though.
Probably is at home in England where they fight under different rules but in the US he is very beatable.
