You've seen "4-Star gets promoted to 5-Star", now, which 5-Star would you like, or at least think would be interesting, to see being demoted to a alternative form 4-Star? (Even if very unlikely it'll ever happen...)

For me, I think a 4-Star Remembrance Topaz that lost her cornerstone and now has to fight using Numby(And maybe other pets) in a different style would be quite interesting!
