Should I get a sliding genioplasty/jaw surgery? (Photos)

I think I would benefit a lot from a sliding genioplasty surgery or even jaw surgery. As I look right now, I hate my small, recessed chin. I think it makes me look younger and less attractive. I think the main reason I have a small lower face is because of my weird bite. I had corrective braces for a severe overbite when I was younger. Ideally I would like to increase my vertical chin height by at least 8mm and add 5mm for horizontal length. Any and all opinions, advice, & inputs are welcomed.
