I want to dress up as Robocop next year for Comic-Con, would I be rare? would I be very unique?

At Comic-Con next year in San Diego, I want to be Robocop, and I want to get a realistic Robocop costume, one major reason why i want to dress up as Robocop is because I want to distinguish myself from the others, I don't want a "Common Costume" of a fictional Pop-Culture character, for example, Batman, Superman, Darth Vader, Storm Trooper, etc. Is Robocop a good choice?
