My general plan is to allow people to walk around / fly around their fingerprints. I find looking at people very closely (as in observing their pulse on their skin type close) can really create a more intimate experience between people. Generally people only observe one another at this scale if they are extremely emotionally close, so learning about a person like this will be a really interesting experience. By making this into a landscape however, I put distance between myself and the subject. I possibly will make it into a dessert with the ridges being sand dunes (shaders?).
I possibly can get a fingerprint on glass and go back to the SEM or use photogrammetry. Also I may simply need to just squish a finger onto a scanner, as I just really need a heightmap that I can then use in the terrain editor to at least get the base effect that I want.
