La Femme and L'Homme are Poser-only products, so I don't think this is necessarily a Daz Studio user.

There are tools that try to generate a match for a photo - though they often rely on maps generated to do quite a bit of the  work. Daz Studio has Face Transfer (for Genesis 8 in version 1 and Genesis 9 in version 2) but that doesn't help with your chosen figures. I can't recall which figures Head Shop supports in its current version.
