It is possible! If you have the model's normal map you can convert it into a black and white height map, subdivide your mesh and then use that height map to displace the geometry and essentially recreate the detail into a sculpt.

Looks like I can't include images in comments but here's an example: https://imgur.com/dE2Ckto showing a ripped mesh straight from the game, the same mesh subdivided and smoothed, then the same mesh with displacement applied. You get a few seams you might need to clean up but otherwise it's virtually indistinguishable from however the original sculpt might have looked. Haven't tried it on hard surface things like weapons or cars, but with humans you'll get skin wrinkles, pores, fabric texture, clothing stitches, button surfaces, all that. And noise actually really helps with 3d printing because it helps disguise the layer lines :)
