Since you didn't specify it had to be pure, I cheated and added a monk & wiz splash:

The monk & wiz splashes let you add two extra feats early on, which this build really needs. It sucks losing the capstone (10 DR and free CLWs); but you still get lvl 9 spells and at least it doesn't hurt your DPS. Plus the wiz splash lets you take the first rank of Flame Manipulation, which boosts your DPS with spells like Fire Storm.
EDIT: it's still a flavor build, of course, but I trust you realize that.
