That wouldn't be too terribly hard. Just design the face in CAD and have it send to a prototyper to create an SLA model. That model could be dyed any color and probably painted flat black. It wouldn't look perfect, but it would get the job done in a week or two. Since there's probably not a huge need for it, SLA would be a good way to make one or two.
I also recently found a process called FDM which can create prototypes in ABS and, if the machine is new enough (a Stratasys Titan machine), polycarbonate. From what I've heard talking to prototype companies, the results don't look as good as SLA, but you can get them done in colors. Or, do it in white, sand it down if it's rough, and paint it flat black.
