Also, you say that the natural attack increase does not stack with improved natural attack without giving any logical reason why it wouldnt.
If you don't think that my statement that both cause you do damage
as if you were one size catagory larger, while neither make you any larger, then I cannot help you. To me it does seem logical. You are size X. Improved natural attack makes you deal damage as if you were X+1. Battlefist makes you deal damage as if you were X+1. Neither makes you actually BE X+1, so the two do not make you either be or deal damage as X+2.

As far as i can see, you can interpret the INA feat in one of two ways:
A. Your natural weapons actually get larger and more powerful, increasing damage.
B. You learn to better use your natural weapons, increasing damage.
In which of those scenarios would adding blades and spikes to your natural attack NOT cause it to be a more damaging attack?
A) INA makes you deal damage because your natural weapons actually get larger.
A1) Battlefist is oversized so that it's larger than your normal natural weapons would be (And spiked, to help with some damage reduction and special abilities).
In this scenario they don't cause your unarmed damage to increase two sized because the battlefist does not grow to one size larger than your one size larger. Now, of course, this cannot actually be the case flavor-wise with a slam attack, because the slam attack can be used with any part of the body, so that would have to actually increase the size of your self, and therefore would actually increase your size. But that point seems irrelevant to me.
B) You learn to better use your natural weapons, increasing damage
b1) You then put on a battlefist, which is larger than your natural weapons actually are... Fortunately for you you're already accustomed to dealing this type of damage. But, of course, you're not better at using these overly large natural attacks in such a way as to be even *LARGER*
C) The feat makes your natural attacks *harder*, and deal more damage
C1) The battlefist is already harder (and spiked!). No net effect if your normal weapons are already this hard.
There. Now I've spelled out more clearly some of the logic behind that.
Now I'll go into something I personally also consider important: In a monk, one increase in unarmed attack is something I think helps balance the class. Two increases sends it well over the top. Now, if you're in a campaign where well over the top is wanted/needed, then I don't see why you shouldn't allow this to stack. Hell, allow the INA feat to stack with itself. And, for that matter, allow the Battlefist for non-warforged, and let them work on already Large PC's.
