This is a hard one for me and I'm on the fence about this. I think this is one of the first centurion applications for ANH stunt with FX chest and back, and it sets a precedent that can affect the centurion program negatively.
While I do like your enthusiasm for modding the FX to the best of it's abilities, There is a number of details, like those mentioned by Tyler, that I'd prefer see adjusted. It wouldn't be fair to the others who also have worked really hard on their centurion to approve anything other than great. Rules are rules, but there are also some gaps in those rules where judgement comes in, since nothing is air tight.
I'm also concerned about your blaster. While it's cool that you've made it yourself, and I've seen far worse, I'm not convince that it holds up to centurion standards.
