Suppose you remove the BA cost from TWF.
Now suppose you balance TWF and GWF such that TWF does equal damage to GWF no matter how many attacks are made (without buffs etc).
Now consider what happens when the TWF get's a per attack damage buff. He's making more attacks than the GWF so he get's 1 more use of the damage buff per round than the GWF. In short, by removing the BA and balancing the styles you have unbalanced the game.
But what if you balanced them around having hunter's mark? Well then you have unbalanced styles when you don't have hunter's mark.
The only fix is to keep the BA cost and have GWF and TWF balanced without any buffs. Then on the first turn you use your BA to cast hunter's mark you take a damage penalty knowing that if the fight goes as long as expected you will make up all the missed damage compared to the GWF (even if he also casts hunter's mark). The downside to this balancing act is that if bonus damage goes up significantly more than hunter's mark or hex can provide then that unbalances things pretty quickly.
