Here is the OP's idea of complexity, find a splat book which rests on an already broken game (base 3.5e) and break it some more while masturbating furiously to how good your build is and then come to complete ecstasy as you stack 20-30 buffs on you. Then ascend into Pun-Pun status. Great experience for the DM and everyone at the table.
I think of all the analogies that could've been used, that's the one we really didn't need to see. Cheers.
