Hey, how bout that Abyssal specialist alternate class feature in Drow of the Underdark. The one that lets you be specialized in spells of certain descriptors, including chaos, instead of a specific school. I don't remember anything but fluff actually limiting it to drow wizards, so maybe take a focused abyssal specialist, that Dragon Magazine option to trade...something, I think familiar, for applying a descriptor for a non-neutral alignment component of your alignment to all spells (except ones that have the opposing descriptor), and some abyssal heritor feats, add in some of your other magery antics, and now we've got spell recycling in addition to all that other cool stuff.
