@Zaiten, nope I do not have anyone in mind for Uranus so you should definitely cosplay her.
If we actually get to pull this off it would be so amazing. <3 Sailor senshi groups are my favorite groups ever, partially because it's cool to have all the matching uniforms. When would you guys want to try and do this for? The senshi uniforms aren't too hard or expensive plus there are lots of tutorials on them.
