I have a hi poly version, but it was meant only for baking normal maps. I've subdivided the hell out of them (for example the shirt went from 600 to 10 000 polygons), pushed all the verts from the low poly version and hand painted some (more or less random) deformations.

The low poly version actually has some details that the hi poly version lacks (buttons, pockets), these details were added only to the texture, and then the texture was converted to a normal map and merged with the baked normal map.
As I said, I can provide the files, but I don't know if they would be of any use to anybody.
