YO I'd like to point out that we try our hardest to come up with unique ideas. Unfortunately we are only human and ideas will eventually be repeated. Also the panda in the bazaar looks nothing like the armored panda (plus you forgot the passenger turtle and rhino). All that said players are constantly requesting hats that have similar structures to older hats, which makes pleasing everyone very difficult, so it'd be cool if you guys could understand that.
Edit: The GST cone hat and the cone hat that was in presents are actually pretty different in shape and overall design.
Ill post a comparison
Edit 2: Like CM said: Messaging any of us GAT with hat ideas that haven't been used is actually greatly appreciated. I stopped advertising it in my status because all the ideas I was getting was "I want old hats" "Make this hat because I always wanted it." which was annoying.
