Deadshot is about the only villain from the Bat ranks to editorial be essentially removed as a member of Batman's Rogues. His Suicide Squad days essentially rewrote the book on the character to the point where if you picked up reading comics anytime from about mid-80's forward you likely just considered Deadshot his own thing as team leader of Suicide Squad. I did. It wasn't till the 90's I found out he was created in the Bat books.
As for the picture of him I must say that just the eyepiece itself looks extremely bulky. Perhaps that is step one as a costume and other accessories come along.
