Feat order & enhs can be tweaked, just wanted to see if we could fit everything in, and the answer seems to be "mostly." Not sure what kinda AC you could get out of this build; probably something a little less than BRC. Monk 2 splash would add two more feats (I dunno what - Stunning Blow & Quick Draw maybe?), but AC gets more complicated.
