Of the KSS that have left in the last year, I feel like Tanapyon and Kurumin might have been chosen to debut if they'd stuck around until now (whether instead of or in addition to the ones that ended up being chosen). I wasn't a Kurumin fan, but I could see she had some talent and energy. I'm sure it wasn't unnoticed, and Tanapyon's talents weren't either (neither was her popularity, as demonstrated by her magazine appearances).
And perhaps Tanaka Karen and/or Oura Hirona would have been debuted too.. although Hirona being as young as Funakki, I feel like they would have been more likely to keep her as a trainee a little longer. Then again, that could just be my bias at liking Hirona & Funakki as a duo lol.
