Riff - I don't think anyone believes it would ever be mass produced. But as others have noted it seems like it would be much harder for a custom shop to reproduce the body panels from pictures (no matter how many there are) rather than detailed CAD models.
You never know what might happen to the prototype - the museum closes someday, they auction it off to some private collector who buries it in a warehouse somewhere. Would be good to get the designs while it's still available.
