Any surgeons out there that think that I would benefit from a chin augmentation rather than lower jaw surgery? (photos)

I have no visible jawline and a receeding chin. I have a deep over jet and when I smile my lower teeth are not visible. My top teeth are very straight as I have had braces and I am very happy with them, however I'm thinking of getting a brace on both upper and lower arch's to help improve any results I may get from a chin augmentation ?? I have included two photos and would be greatful for any advice or previous experience people may of had?? Thanks in advance
