PhilC's face putty is a wonderful thing, but with the standard 'cage' it takes a quite strong computer to run smoothly. Maybe less magnets could be used to improve performance.
The advantage of face putty is that it is easily adaptable. It reads a mesh file and positions 'nodes' at the vertices. The nodes, represented by small sphers connected with cylinders, control magnets that work on the head geometry. If you tailor the mesh for Antonia, you can use it for her.

What is missing is a built-in symmetry facility. A few dials like the ones you find in the face room giving direct control over features (jaw, cheeks) would be helpful also.  

FacePutty comes as part of the Poser Toolbox. I am not sure if a generated cage with magnets can be distributed within the license.

For a specific figure like Antonia this of course can be mimed with a magnet set with controls. 

Of course the face room is more than just geometry. It is also texture.
