In theory, you could remedy your boss's "left-handed blaster" debacle by adding a shoulder-braced stock. Just a bit of a wire loop is all it needs to be. And then train your troopers to properly aim them like rifles. Presto! You have accuracy. Then add a little strip of fabric (or Ewok hide) for a sling, and they don't have to awkwardly carry the blasters in their left hands either!
I'd be willing to supply the Empire with this upgrade kit for a reasonable fee.
Obviously the helmets are still a problem, buy they could be left off anyway.
I appreciate your ingenuity. Unfortunately I have learned that my boss will somehow screw this up. He would make the wire loop too short or make it out of some sort of flimsy or flammable material.
That is why I offered to supply these materials instead of you worrying about internal issues.
