A few variations:
1) An Archivist 7/Hathran 6/Chameleon 1 can apparently know and spontaneously cast any spell (divine or arcane).
2) An Archivist 7/Hathran 5 can know and spontaneously cast any spell with a permissive DM allowing all possible sources of divine spells.
A level of Wu-Jen could be thrown in for an extra spellbook to raid. There are a handful of really nice Wu-Jen only spells.
