Hey sotacs,
Looks like a pretty cool idea, and I would probably go for one.
My only suggestion would be to somehow blacken the cut edges of the metal so you don't see the raw metal under the paint. In a couple of the pics, the raw metal reflects too much (I would assume it looks similar in real life) and it takes away from the effect of having the light shine through the shape. I think it would look a lot more professional and clean if it was solid black.
Just an opinion,
Stryker
