Just wanted to voice some support and agreement! I've been deeply disappointed about this, so thank you for bringing it up. I would love to see more spawn Astarion kiss(es) since it is unbalanced right now. But I disagree with reusing the bite kiss. Spawn Astarion says that he asks before he bites. I don't recall all of the AA kisses, but I'd be fine with reusing anything that still fit the different characterization.
