Just shooting from the hip here, and seeing what can be cobbled together...
Sorcerer 6/Incantatrix 5/Sanctified One of Kord 1/War Mage 5/Spellwarp Sniper 3Would have 4 free metamagic feats, Metamagic Effect for persist tech, and the ability to turn Fireballs into rays. Now, take the usual damage boosting feats, and sculpt spell. Fireball is now any shape you want, doing untyped massive damage. Reserves of Strength to uncap spells. Take Miser with Magic, using Unfettered Heroism to recharge 1 slot/round. Congrats, you're now a warlock on crack
I know I can do better though...
