Can a sliding genioplasty be customized to widen the chin and also increase projection at the same time? (photos)

Can a sliding genioplasty be customized to widen the chin as well as increase projection at the same time? I have a narrow pointy chin that is also recessed. In order for it to look good, I would need to change both dimensions. If I just increased projection the chin would look even more pointy. (Pictures included).
