I would recommend you first test with either a limited number of variable feats, or a "feat pool" like a wizard's spellbook.
Was gonna say a similar thing until I read your post! If you start off with your first floating feat with the choice of 2 different feats, then gained another 2 options/floating feat, it would make sense. You could basically have a backup feat-tree, go power attack if the combat expertise isn't helping, etc.

So make a house rule on standard action attacks based solely on BAB. That way any class with better than worst BAB gets a piece of the action eventually.
All I ask is a tall ship, and a star to steer her by.
