Sounds like a fun job to do FATES with but lacks AoE but if that is intentional then need more potency or it wont be so preferable in endgame and dreaded when queued in on a DR group.
So more potency or more AoE or it'll be a gimmick job like one that I shall not name >_>
No hate on the idea tho, I really want to BST again xD
