If you're allowing the classes from the added sources, you may wish to update your classes permitted list.
That said, I'm thinking perhaps of a Warlock/Dread necromancer, if you'll allow. It may take me some time to get the sheet up. I'm running a bit behind as things are hectic around here lately. (Working on two sheets for other games, and things IRL are picking up lately)
Btw, did you get access to Complete Mage, or just Adventurer/Divine/Arcane?
