So which members would appear on KBS' The Unit (idol reboot)?

The Unit is an upcoming idol project group show featuring "failed idols". Which current or former members could possibly appear? Apparently they've had at least 350 people apply so far. Do you think Star Empire would send our girls on the show? Or should we just hope that we see former members pop up on the show? I would LOVE to see Sera or Leesem on stage again but who knows. With Hyuna getting married in September I'm not sure if she would want to sign up, or Minha with her acting career now.
