Not that I know of. I don't have a scanner myself, but since I have a
Solidscape, which is the RP machine you'd probably be looking at for
printing the miniatures, I'm often asked about this type of project.
My understanding is that if you want to scan something and reproduce
it at a tiny size with a fantastic amount of detail, it's best to
start with an object at least a foot in size.
Bigger doesn't hurt...the other day I talked to a fellow who wanted to
have me print a two-inch motorcycle charm. His clever idea was to get
a plastic model motorcycle and scan it for reduction. This would work
if the model's a good sized one, but the guys with the scanner felt
that for best results he should use a real motorcycle: they'd
spray-paint it a flat color and scan it. I had to tell them the
project budget wasn't up to that.
In all seriousness, maybe your best move would be to consult people
that do reenactments, get a good-looking fellow to dress up in full
uniform, and scan him? Any of the big scanning bureaus could handle
