I would suggest that you wait until you have reached your long-term stable weight prior to seeking consultation with board-certified plastic surgeons who can demonstrate lots of examples achieving the types of outcomes you would be pleased with.
Then, communicate your goals carefully. Learn about the pros/cons/risks/complications associated with the operations discussed. Achieving realistic expectations will be important as well.
