So the way I normally get this map is by simply converting it from the normal map

What I've always wondered is if there's another way do do it, namely, without the need of a low poly model?
Was just thinking it would be nice to have a high poly model with UVs that I can somewhat texture with the aid of this map, say in Ddo or Substance Designer, without needing to retopo and go through the normal map baking first.
Or am i just dreaming.
