They reworked Trundle because he didn't fit *anywhere*. At least Morgana and Kayle have each other to kill, and they've subsequently been tied to Demacia vs. Noxus. Trundle always has been on his own, and he was unpopular, so they made him fit the world. Besides, Morgana and Kayle have had so much more established than just their written lores. Reworking them would negate a lot more than it did for Trundle or Karma.

That said, I do think Thresh is a likely possibility, even though I would strongly prefer that Lucian be tied to Evelynn. I'd want to see it be that whatever she went through turned her into the Shadow Isles monster she is now.

Another important note: Thresh and Evelynn don't have Twisted Treeline altar quotes yet. Lucian may finally be the avenue for Riot to give both of them lines.
