Here's my quick response:
(1) Do the flaws make sense? Is there a logical reason why the character would suddenly be afflicted with these? If not, can a logical reason be found? Can they be incorporated logically over a longer span of time?
(2) I would be extremely careful in vetting anything taken from Ultimate Feats. The book is a cheese depository of questionable design.
(3) Retraining can't be done all at once. It looks like this plan will take him until at least 19th level to fully implement. I see no reason to let him get away with instantaneous retraining in a way that radically revamps the character.
I'm generally pretty lenient in letting people rebuild their characters. Campaigns can last for years and, if a bad choice gets made for some reason it doesn't make sense to force someone to live with it. But this scenario seems way out of whack.
