First off, Dot. This is really cool, if extra bookkeeping. Giving options to classes that don't rely on just magic is always good.
Second, I wrote some custom work based on iterative attacks from the point of view of weapons (weight, length, and maneuverability). In a nutshell, the smaller/lighter the weapon, the more attacks you get each turn.
I would love to merge these two concepts together, I can see it working pretty well, but I am not sure if it is totally broken or not. Opinions?
Third, A few feat ideas.
Improved maneuvers: drop the price of adding a maneuver by 1 (stackable, minimum cost of 1 per maneuver).
Extra attack: you may create an attack routine that has one more attack than a character of your bab and level could. Your total bab does not increase because of this extra attack.
Defensive offense: when your attack routine has less attacks than normal for your bab and level, you gain a +2 shield bonus to your armor class; you may also increase this bonus by lowering your total bab for an equivalent amount.
Damaging maneuver: when you add a maneuver to one of your attacks, you can voluntarily give yourself a penalty to your cmb roll for an equal bonus to your damage.
Married to my (enter weapon here): when adding (enter maneuver here) to any of your attacks, if you are also wielding (enter weapon here), you gain a +2 bonus to the cmb check.
