Over and done with when the soon leave the Wish Realm. From a practical standpoint, Jared probably will not be able to carry the role of an arc villain, let alone a Big Bad. It would be foolish and cringeworthy if they choose that over a more establish actor that can bring in new ideas to explore (aka Henry is just Henry and there's no new story to explore with him).

Oh, and he's easily killable, trapable, defeatable, and manipulated. Once sort of powerscales their villains in durability (Hyde, EQ), manipulation (Ingrid, Rumple), wit (Zelena, Pan), outright power (most of them), and that's about it. Sir Henry has none of those. At best, Hook will do the heavy work and knock him out during an easy sword fight and they'll place him in a magically guarded cell.
