Unless most of the past characters return, it would be weird to make unit dresses for all past units when some idols are absent in current DCD. I think they'd revive only one character (in this case I guess it's Seira or Mikuru, hinted by the best duo clue), so Masquerade, Skips, Dancing Diva won't be the available options.
