Holy balls, a DMC neon sign on the wall would be awesome. @_@
I bought a friend one of those neon reflector signs a couple years back - not a glass tube, but like a piece of perspex which has a design laser cut inside it and it reflects the light that's on the top of it. It looks pretty much the same as neon tubelights when lit in the dark. I assume you can get those custom, if you wanted a more accurate design. As well as glass tube lights if you wanted the authentic look. Either way... awesome idea. I love those neon lights.
