It is important to note that while your idea doesn't work mechanically, it doesn't mean you can't play it out in game. All base attack bonus means is the number of attacks you make in a round that have a reliable chance to harm. While you're still young and learning that may mean that several of the people you do this to duck, or the blade clinks off their armor, or what have you. As you grow higher level and get a larger number of attacks this same maneuver (sadly sans the movement) can improve (ie. you get more attacks).
Alternatively, the overrun and combat reflexes approach mentioned above works (probably works better in fact).
So within the default rules I can spread out the Base Attack Bonus's implied damage? Nice.
Becoming massive and fast doesn't increase this BAB does it? Also thanks, first 'this could work' response yet =D
