Should I get Invisalign, Veneers, Palate Expansion Surgery or a combination off all/some treatments? (photos)

My mouth is small. Very small! When I was younger my dentist & orthodontist agreed upon pulling my upper canine teeth instead of using an expander to create space. I then had braces which created straight teeth, but left me with an overly small mouth. Its been 13+ years since I've had braces & my dentist is now recommending Invisalign to correct crowding. I want to know if it's worth the cost. I would like my mouth to look more aesthetically pleasing & have a larger smile- if possible.
