I think a Disgaea version would be interesting, or chaotic since many of the characters will fit in to five+ squares.
Then again it is hard to get more Chaotic Good than Etna or Lawful Good than Flonne. Kurtis would be somewhere in the neutral cross. Mid Boss spans from Chaotic Neutral to Lawful Good. Laharl has moments in every square. I think Pleinair couldn't even be on the list. <_<
