Let me start by congratulating Paizo with this bold move!
Moving on to the important stuff:
Having a Skill called Acrobatics and a Feat called Acrobatic is going to get... problematic (people are going to get confused). I would suggest changing the skill name to something else (suggestion: Stunts), or you could keep the old name, Balance.
All the feats that only add +2 to two skills are incredibly boring, they really need some love. I would suggest adding an ability to the feat that isn't incredibly strong but still unique to the feat, this would motivate folks to choosing these kinds of feats. An idea might be to add the ability to have critical successes with these feats, if you throw a 20 while performing a skill check you score a critical success (if you confirm it, same as with combat critical hits). Alternatively, if rules are already in place for critical successes for skills (or are added) increase the threat range by one for the relevant skills. What the exact results are for each critical success are of course skill dependant, but think along the lines of faster completion of a task, or additional bonuses on Opposed checks or bonuses to future/next attempts.
