One of the Ascended Astarion kisses (the one where he looks at the neck) was originally a Karlach origin Act 2 kiss (assuming that wasn’t a bug or something). That could be a good option if they want to even out the kisses between the two paths without creating a new one.
IIRC that was there accidentally for testing or something? I don't know how the bug got there, but it required for you to change bodytypes (to type 2 I think) instead of using Karlach's for it to play correctly. It was also extremely broken, but I recall back when they were uncovered everyone assumed they were actually a WIP for AA.
From what I can tell from yt, it has been changed for Karlach now too so they have one of the Spawn kisses instead.
