I could see PLD getting some support capabilities. Maybe spells cast on a PLD are amplified in some way. Perhaps PLD gets a Sacred Prism spell. Spells cast on the PLD are shared amongst the group. Stoneskin on a prism'd PLD gives stoneskin to everyone. Give a reason a PLD could OT.


Remember Vivi and Steiner's partnership abilities in IX? Vivi would cast an element on Steiner's sword making him do elemental dmg. BLM cast Fire on the PLD, makes next WS an AoE or something. There's no elemental wheel so dunno if that would work.


If nothing else, have Cure go off VIT for a PLD instead of MND.
