Unfortunately the answer "none"! as bane ball-hinged mole is relativity small, therefore the only closes fit i could find were the trooper with face/removable helmets.
why would you fit Cad Bane head onto a troopers body, you ask?
Cause in the final session of the CW, the Session 2 preview has a scene of Bane in Trooper suit and judging from the helmet, it looks like he is in clone trooper "Denal" armor. (image shown below)
Here the scene grabs if, you are still unsure of what i going on about.....
Now you have seen the screen grab from the session 2 preview, here's my version of Bane in a clone trooper armor, had force its head into the clones ball hinged socket.
(please note, that this is merely a custom done by me and its not for sale)
Put on the helmet...
