Oh...SNAP and a half! I would love to jump in on this if there is still time and opportunity! I remember coming up with my own Sailor Sun, (There are a bajillion versions of this senshi that so should have made it into the series.) and I am familiar with the entire series. I can still give the english translations to the senshi's Japanese names, remember all of their attacks and such because it was the first anime that I came across.
If possible, I'd seriously love to play my sun character, though I can just as easily play Setsuna/Pluto or Rei/Mars since personality wise they're more comfortable for me to play. I might even be persuaded to do Michiru/Neptune.
