Thank you, santicor, for elaborating further on my short answer.  I was stepping out and pressed for time.  The workflow appearing on the other posts indeed point out the critical details how to correctly export and import for morphing V4's facial features.  Nruddock does caution that too much alteration of the mesh will cause problems later.  So carefully consider what you are altering and how to approach the project.  You can get very satisfactory results if you think it through.
