How about a SaGa-style system with LP and in-between encounter recovery?
For those not familiar with the series, when you are rendered unconscious in battle (0 HP), you lose 1 LP and continue to lose 1 LP every time you are hit while unconscious. When you lose all LP, you die. The nice part of this system is that you can be brought back from unconsciousness by simple HP recovery as long as you have LP left. When battles are over, HP and other depleted stats are recovered immediately, except for LP. The only way to recover LP is to rest at an inn or drink a rare potion, something to that effect. The amount of LP available per character varies, but is usually single digits.
I think that would give XIV an interesting layer of strategy. Make it so you don't need a dedicated person to Raise, anyone who can restore HP can bring people back to consciousness. You wouldn't need to worry about recovering between battles, but in a long sequence of fights, you have to be careful about your LP. If you die, there is no way to recover, you simply have to return to your home point. Add to that some powerful desperation moves that actually consume LP and you have a very big factor of risk to play with.
