Silly. Star Wars costumes are already pretty samurai-inspired already, simplified mostly because of cost reasons. Some of the early concept art is even more samurai-esque. Darth Vader's helmet is definitely a samurai helmet. Then there are lots of other samurai-Vader artworks out there already, including action figures and statuettes.
And BTW, a samurai should wear both a Katana and a Wakizashi. The Katana should be worn with the cutting edge up so as to not wear it unnecessarily and as to be able to draw the sword and make a downward cut in the same motion.
BTW 2. Boba Fett (the real costume) has keyboard keys on the shoulders. They are probably from a point-of-sale keyboard. I have not identified the correct type yet, but Devlin's are close.
