which big company groups could disband without impacting the company too much?

Day6, Exo, super junior, tvxq, snsd, red Velvet, ikon, winner

not people mentioning literally every group that exists smh

Dont get me wrong I'm a once but i like think twice because in terms of physical sales jype already has straykids and itzy has international hype , niziu doing excellent in Japan and jypngg going to target korea i guess.
