I definitely don’t think they’d get away with killing off Luanne and Lucky. I think the sting of an orphaned Gracie would be a bit much. My own feelings are that Luanne and her family will be referenced as offscreen in phone calls, etc., where we get infrequent updates through Peggy or Bobby, and eventually the characters are seldom, if ever, mentioned again until the eventual revival finale.

Or maybe they’ll recast them, who knows.
