This is not a bad idea. Not bad at all. The problem with it is that there is so little material to work with to make it a satisfactory cliffhanger. We are hardly introduced to the Chikdren. At least the night king has a presence.
I think it wouldn’t be as bothersome as we might expect it. There will be a mystery left about the children, more than now for the maybe-prequel show.
