Only 2 - Freecure and Overcure and they could just get switched when Cleric Stance is up (assuming they'd alter CS when GEO is equipped) to Freestone and Overdraft using similar or same effects for Stone/Aero. MND traits can stay (SCH keeps INT traits). Others enhance supporting abilities.
Cure is a non-issue as SMN gets Physick.
Cure II & III, Medica & Medica II offer the team support in a tight situation. Instead of a BRD replenishing WHM MP the GEO could help heal a little bit as well.
