Just to add complexity to the mix... shorter hair is more comfortable (and easier to manage) under a wig that long hair.
So basically, your shorter hair cut opens you to any character that strikes your fancy - just get a wig of appropriate color / length / style and you can be that character.
As for the set you've listed, Nobu or Setsuki would be great since they're rarely cosplayed (the more variety of characters at a convention, the better.)
