Red Mage in the form of spellbladery as a Duelist promo, here on SL2? Hell yes. Maybe the class could function as its own "Shapeshifter"/"Boxer" role for Duelist, receiving a buff or two when critting and using spells in the same round. Or rather, working your way towards it slowly but surely and increasing Eva/Crit or Magical DR through time when using magic in conjunction with basic attack.
Defensively, maybe offer some magical interaction with Riposte or Eviter?
