What could have been - Chewie with a bionic arm in TFA

This concept art that came about before the release of The Force Awakens is Chewbacca is quite novel as it suggests our favourite Walking Carpet could have had a bionic arm. Phew, that was a long sentence but how cool is that?!

This could have been a great way to continue the grand tradition of people losing their arms in a Star Wars film! Could have made a great backstory moment too!

Amusingly, it was C3PO that had a new red arm in TFA! It was quite a cool little story.
