This is a great idea
Assuming the counterfeiters were trying to produce perfect copies of the original item. Unfortunately they're not trying to produce perfect copies so any measures designed to prevent that are a waste of time.
I *suppose* there might be a very small niche for authentic counterfeits - certain high value collectible items - but I don't see the material acting as a huge impediment. If someone has possession of the original they could just dust the thing in talc or similar, or just create a mould from the original and scan that. Nuisance value, nothing more.
