Ability draft would be awesome, though I don't think that League's abilities are modular coded (as in, you could have anyone use Vayne tumble). The simplest thing to do would be remove champs who just are too strange to work, such as:

Karma, Rumble (heat?)

The other issue really is just the spell costs, since in DotA everyone uses mana so there is no issue with say Mordekaiser taking Swain ult.
