Trying to implement one as a Caster would be forcing a square peg into a round hole, just because you want the hole filled and are ignoring the other pieces available. It would be like trying to implement a Gunblade-wielding healer for the sake of having a Garlean Gunblader, or a Hammer-wielding ranged job, or a Pistol-wielding tank.
There's "plausible if the devs push the boundaries to unleash their creativity," and then there's "plausible if you have a pet smeerp and a patent pending for a time machine." Somehow I get the feeling giving a job 15 variants on Enpi or Lightning Shot would lose its creativity real quick. Lord knows it would already take enough to give them another sword variation we haven't seen yet.
The series already has Geomancer, Time Mage, Necromancer, Green Mage, and any number of Maguses, Mystics and Wizards who could fill a Caster slot, and still offer unique gameplay doing so considering Black Mage is probably the only "conventional" spellcaster job we actually have. Even ignoring largely pedantic arguments about how certain ones are unlikely for X or Y reason, throwing all of those options out the window to implement a Rune Knight "Caster" would almost be insulting to the players who were hoping for more spellcaster options.
