There's already one of the ESB bounty hunters in JO..
The Trandoshan model.. one of the bounty hunters, Bossk, was a Trandoshan.. they hunt wookiees for sport and their pelts.
The others would be Boba Fett, Dengar, IG-88 ( all of whom i have in my wishlist
), and the bounty hunting team consiisting of Zuckuss and his bio mechanical droid, 4LOM ( who thinks he can learn to use the force ).
I think i will put IG-88 at the top of my model wishlist for now, since it would be fairly difficult to make a faithful model for him, and whoever does it, will most likely do it right.
