And how about Ajimi, Aroma (even thou she is my least fav) and Shion (like what you said). I understand Shion because even she didn't appear much in the Op she is part of main 6 girls and I believe that she will get more appearances. The problem is with Aroma and Ajimi, they also didn't appear in the Op and they're not part of the center 6 (but main charas). Anyway, your theory is great and I can imagine all the main characters will defeat Hibiki together in the end.
