A lot of similarities between Bahiyyih and Wonyoung. Both are extremely popular members in their respective Mnet groups. Any group that picks up Bahiyyih is guaranteed a good amount of album sales and extremely strong following. Also, there's the family angle you can play at with her and her brother.
With how Hybe acquired Chaewon and Sakura when Iz*One disbanded, I think this is a legitimate strategy for Hybe to pursue and build another global girl group with Bahiyyih and maybe one or two Kep1er members.
