Here's someone with a pretty good Goliath costume at the Gathering of the Gargoyles in June 2006. The Gathering is the annual fan convention for Disney's Gargoyles animated series, which always includes a costume contest. This was one of the prize winners that year.

I apologize for the poor quality of these pictures, but for some reason they had the room extraordinarily dark which made it pretty difficult to get a good picture.
