I took a look, the only one I'd consider semi-reasonable is Improved Unarmed Strike and a bit of Dynamic Unarmed Strike.
There are a few changes I'd make though.
Improved Unarmed Strike: 1d8 is a little high I think. Monks in 3.5 only started with 1d6, so I go with 1d6. Also, I never noticed that unarmed attacks didn't already have the off-hand property.
Dynamic Unarmed Strike: For a lot of these, you're giving powers that should actually be reserved for certain power sources, such as Ki. Also of note is that all the feats that give extra powers to weapons are paragon tier, so that's what this should be. The only choices that should be available then should be versatile and high crit, which make sense.
You may want to throw on some Strength requirements for these feats as well.
The power feats are just plain broken, sorry. It takes specific combinations of powers, paragon path and epic destinies to be able to reuse powers.
I hope I didn't just completely drown your parade.
