A labor-intensive process, no doubt, but also probably automatable if someone took the time to do it. Could make an interesting proof of concept. :-)
Are you thinking of the Game Boy screen cards? I think there's an older example too, from Belville or HP...
Possible? Maybe yes.
But the amount of tiny triangles is likely not worth it. Might also make the model very hard to handle for renderers.
IMO this would be the best example for a technique like the heat sensitive UFO sticker - just make one simple file for each individual "frame".
