Most of the surgeries I'm aware of make the shoulders and chest broader so that the hips look less wide in comparison. You'd be surprised at how much its about ratios compared to actual size. Things like deltoid implants, lat implants, fat grafting, and my favourite - clavicular lengthening. Its complicated to explain how that works but to sum it up, it's basically leg-lengthening for your clavicles (shoulder bones). Last time I checked Dr Epply did them but I'm not sure if he still does. As far as I'm aware there are no long term complications.
On the other side of the coin, the only things I'm aware of for hips would be liposuction (if it's due to fat) or an illiac crest harvest. The illiac crest harvest is usually used when someone has gotten into an accident and needs bone tissue to be grafted onto an injury. I haven't been able to find information on this ever being done for cosmetic reasons but I'm sure you could convince a doctor to do it for cosmetic reasons if you had the money considering this surgery is performed thousands of times a year and is relatively simple. They don't take much bone off but a bit shaved off in the right place can make quite a difference.
There are other ideas I have but you would need to talk to a plastic surgeon and discuss ideas. One thing I've thought of is perhaps taking fat from the lower body and grafting it onto the upper body, especially if you have a bad fat distribution.
Of course, these are all assuming you have the money and are willing to go through with surgeries. If not, I'll write a little section here about my other ideas (other people reading this, see my above post for extra generic advice like gymcelling etc).
An idea that I've found several times while scouring the Internet is a practise that I've coined the term 'belt binding' for. The premise of this is tying a reasonably tight belt around the upper pelvic bones for extended durations of time. This essentially curves the upper lliums inwards and upwards, honestly sounds retarded but other people have preported to have gotten results from doing this.
Referring back to the post I've written before. Some other gymcelling techniques could help build up the upper body. Breathing chest pullovers can help widen the ribcage by increasing lung capacity and expanding the diaphragm. Since the shoulder is connected to the sternum, this will help widen the shoulders aswell. Even Arnold Schwarzenegger claimed he had gotten expansion from this.
Didn't it seem that the bodybuilders of yesteryear had bigger chests? (We're talking chest circumference here and not pec size, mind you.) Ellington thinks so and he knows why - it was all due to the all-but-lost art of ribcage expansion.
