The ingredients are all there already. I feel the only thing their arc needed was for the show to introduce the reveal about their true nature (pic related) a little earlier and explore the same doubts, jealousy, and anger they feel about their condition throughout the different episodes. The ending of their story is perfect as is; it just feels like the show wasted the vast majority of their confrontations with the Senshi without using them as a source of their inner conflict, like the last couple of episodes do so well.
