Should I get double jaw surgery + genioplasty? Am I a good candidate for genioplasty? (Photo)

I have a bit of a underbite. It's not severe or anything like that. I eat, chew, talk, or breath fine. I just want this for cosmetic reason. I have always wanted to fix my jaw since I have a bit of an underbite. I can hide it very well. Strangers can't tell I have an underbite but it's something that I am concern with my appearance. Would DJS + genioplasty be good on me? I heard LJS + genio would only be necessary in my case. Below are an x-ray of my bite. Yes, I have braces on.
