Aren't the multicolored Lanterns a successful concept? More is more except when less is more and in this case I don't think it is. Currently we have Wonder Woman, The Sensational Wonder Woman, Wonder Girl and Nubia that all need storylines. Donna and Cassie could probably support their own book or at least a limited series. So could Grace Choi or Artemis and Hippolyta is in the Justice League. If you build it they will come, I say go big or go home.
