Ok, so I finally came up with those feats (I've been working on other things as well in the meantime, such as those races). Anyway here they are, as well as my take on some of the others (I left the half-elf the same):
Dwarven Commander [Racial Variant]

Yes, I do realize I have two wizard ones in there, but my yaun-ti are actually good for most of the other classes, and as we realized earlier, messing with dexterity and strength should not be done.
As well comrade raoul, I'm putting together a PDF of feats for my campaign, and just wondering how I should credit you for this idea.
