To be honest, it is a bit odd that PLD doesn't have any curative abilities at all. Classic FF Paladins (of which FFXIV's PLD is clearly meant to be an example, regardless of whether it's "Knight" in Japanese or not, what with the CNJ subclass requirement and all) have always been front-line fighters with the ability to cast some healer/support spells. In this game, though, they don't have even a scrap of healer/support, except for what they take from their CNJ subclass (and even there, Cure is too gimped by lack of MND to be worth cross-classing).
It'd be nice to see PLD get back in the saddle as proper "holy knights" again, and with the level increase coming with the expansion SE has an opportunity to do just that. Maybe not something as overwrought as the OP's suggestion, but when a visceral, bloodsoaked class like WAR has better native healing ability than PLD, something is clearly wrong. :P
