Hero replacer.

I hardly touched the original textures; I used the source files from here, except that I upscaled the faces using GFPGAN. In my opinion, they are of good quality (there is a comparison there), at least they are definitely better than the original.

I see... the fact that it's better than the original... is possible, however, if you're going to resize, it's better to use specialized utilities! There will be less blur in the end... on large monitors (larger than 24"), this defect is visible!
