fiberglass grille?

I have a camaro and I can't find a decent grille so I was thinking that I could fiberglass a custom grille for my car. How had would it be to make a fiberglass grille? And would fiberglass hold up as a grille cause I haven't seen it done? This is my first time attempting fiberglassing so if anyone knows what to make the frame out of or if someone has fiberglassed a grille before, any help would be awesome.
