Contrary definitely is released, so that set isn't illegal. If you'd like to propose that set, please review the formatting guide and be sure to follow ALL standards. I haven't played enough NU to know if that set is viable (it looks usable), so go propose it in the NU analysis subforum. That set looks rather annoying to face, though it's going to have issues with a lot of the NU tier, as it is very offensive. In any case, good luck!
