Yes I have and I'm not really a fan of the approach.
The real difficulty of the approach is evident when you look at the treatment of the Fighter in the Advanced Player's Guide. All of the sudden the elegant class is replaced by a hodgepodge of fixed progressions. This obviously raises the question which the Pathfinder fighter raised for me when I first looked at it: why must I be saddled with this fixed progression of powers? What if I want to be a fighter that doesn't wear armor, for example? And sure enough, that's exactly the problems that the Hodge Podge tries to address. But of course, it doesn't really fix the problem, because, for example, what if I wanted to be a 10th level crossbowmen and a 10th level basic fighter and select a bit from both ability chains? Because they are ability chains and not feats, I can't really do that but from a standpoint of reasonableness and balance there is no reason to restrict a player from that.
So, in short, I believe that the fighter I've described pretty much does everything the Pathfinder fighter does (and to the extent it doesn't, it could) and more but by avoiding being saddled with fixed class ability progressions it opens up a lot more flexibility for you to custom design what sort of fighter you want to be.
