Don't worry about that.... Cooter is just being Cooter!

Besides, Cooter, you can't be claiming canon when you aren't, yourself!
You should contact Daverian here on the board. He made an awesome mini-gun for his TX (all black stormtrooper). That might be something to look into. I am sure Dave can save you a lot of headache when it comes time to assemble this weapon. Seriously, if you want a costume that would compliment the mini-gun, I would do the black stormtrooper.
Not trying to take you away from the Arc Trooper, but a stormtrooper is one of the easier kits to get a hold of. If you don't get the plastic in black, it could always be painted. Just an idea.
Paul is in your area and can give you a lot of good advice on how to put the armor together.
