Texture Shape Adjustment in Photoshop Needed

I have a genuine facetexture that is applied to some 3D heads, male and female. I want to replace this texture with two highres textures, one male and one female. The problem is that the textures I have can't just simply be scaled 1:1 toward the genuine texture I'm using now because the width of the eyes, the height rations between eyes and nose and nose and mouth are different and so on. I need the highres textures resized so that they match exactly they eyes, nose and mouth of the genuine texture so that I can simply replace the old texture with the new ones. This must be done for one female texture and one male texture.
