A dragon gish I did once upon a time went something like this:
Dragonborn (Heart) Raptoran Sorcerer 1/Fighter 1/Sorcerer +3/Fighter +1/Spellsword 1/Abjurant Champion 5/Sacred Exorcist 8
Feats: Dragon Heritage (Copper), Quicken Spell, Power Attack, Combat Casting, Accelerate Metamagic (Quicken), EWP (Spiked Chain), Improved Flight, Arcane Strike, Versatile Spellcaster, Divine Might.
You end up with 16 BAB and 18 CL, a pretty sweet air elemental familiar, the ability to use up to an 8th level spell as a SLA 3/day, AC goodies and sacred exorcist goodies.
