Lower jaw surgery, braces - will any of this widen my smile? (photos)

I am about 7 months into wearing traditional braces. I will be undergoing orthognathic surgery in approximately 6 months to correct my under developed lower jaw. Will any of this help me reach the goals of a wider smile? I'm a 35 year old male. Although my teeth are straightening I do not feel that more teeth are showing yet and my smile feels tiny. Will my teeth move closer to my lips at any stage for a more effortless smile? Any advice would be appreciated.
