Man, just pay the licensing fee to the greedy Star Wars guy Lucas and use Admiral Ackbar. It would absolutely be the best mascot of all time.
And, oh, by the way, the 3 most recent Star Wars movies were absolutely awful. No humor, wooden dialogue, bad acting, etc. etc. Wretched.
Hate to break it to you, but the Star Wars franchise is vastly overrated. I am old enough to have seen all the movies first run in the theater. At that time the special effects were over the top awesome. But the acting, direction, and dialogue have sucked throughout the entire franchise.
