A combination of a powerfull/usefull devil fruit combined with one that allows you to somehow be underwater, like creating a shield around you but not a normal df shield but one that changes the water itself or blows it away so that the water won't be able to nullify your abilities, it is possible otherwise Aokiji should not be able to freeze water on contact. (still strange though that he can, that means he also can freeze seastone stuff)
