Magus
Eldritch Scion - I like the sorcerer version of the magus.
Wizard
Spell Slinger - Gun Mages are a cool concept I can get behind.
Siege Mage - Currently playing one actually, and these guys are underappreciated power houses. Plus, there's nothing like a wizard preparing a weapon several times their size and aiming it to drop a Roc from the sky.
Sorceror
Crossblooded - Because one can never have too weird of a heritage
Druid
Urban - Mostly because the very idea of a city having a spirit a person can tap powers out of amuses me
