Boingy! Boingy!
Given that no one has stepped up to play Gordon the warmage in your other game, I would be willing to play him and let Menno remain a sorcerer in order to keep some continuity in your games. I'll get to try out two different casters that I've never had a chance to run.
Gordon I would keep basically as-is, I'll have to look over his equipment.
Menno I would change to a Draconic Heritage sorcerer, and his other feat would be Draconic Breath. I would change Magic Missile to Sleep, and probably swap some equipment.
Works for me.
