Not sure if "10 high-res pictures of the object from all angles instead of a model" saves any disk space at all considering models in games are usually just one high res picture uv wrapped to vertexes. Also, creating new content from GAN might not be super appealing for the artistic qualities of the game. Why not do what Escape from Tarkov seem to do with photogrammetry on real objects? Many props like soup cans, couches, whole environments, weapons, can be acquired in real world reasonably easily.
