What you can do is simply disallow any action that would provoke an AoO. That's really their function; they're not meant to kill you, just punish you for doing silly things like casting spells in melee. This will change things somewhat (eg make the Combat Reflexes feat useless), but it wouldn't break the game.
The downside is that you'll still have to go to the rulebooks to figure out what would provoke AoOs. But that's not really that hard. As said, the rule basically is that if you do anything silly, people get a free swing at you. And if you've got your head around that concept, well, there wouldn't be any problem with AoOs anymore....
