Nope can't say I have ever seen anything like that. Though it sounds like you are already on your way to making one of your own.

In all honesty though the stat differences are rather meaningless at that point in the game, and will have almost no bearing on your play through. If you are really concerned with having the best stats possible you are better of going with the level up/down trick. (Level down in a crappy class and level up in a good one repeatedly)
