Getting genioplasty - should I ask for a vertical increase as well? (Photo)

I am getting genioplasty to help with my recessed jawline. Should I also ask for a vertical increase as well? I feel like my chin is too short but at the same time worry about my chin being too long if I ask for a height increase without taking into account that my chin may appear longer after the procedure. My face is a square shape but I'd like it to be more feminine.
