For me personally, any SAM sword that has deviated from the traditional blades have been quickly chucked or glamoured over. However, I can still support SAM swords that differ. A couple jobs come to mind with basically completely different weapons: MNK has tonfas and bare hands, PLD have been seen with clubs, and giant hammers for WAR. Sometimes I even wonder if you replaced DNC chakrams with twin whips if it would immediately just work.
