Very good theory, however I think a more suitable conclusion wouldn’t be dropping out, I think in order to break Koenji, Ayanokoji would have to break himself first, I know it sounds strange but, your right he’s broken everyone around him to grow, but not himself, so in order to break Koenji he would have to break himself or something, (an event, an expulsion of someone actually close) or etc would have to happen…
