Would a revision be likely to improve my nose or make it worse? Want to build up nose bridge. (photos)

Hi, I'm over 6 months post-op and incredibly upset and distressed by my primary rhinoplasty outcome. All I asked for was the removal of the bump on my nose and nothing more, but instead my doctor was incredibly reductive and left me with a very sloped dipped nose. It has also settled lower than he anticipated because he took out too much septal cartilage during my septoplasty. Would a revision to build by bridge back up with some kind of graft or cartilage have a decent chance of working?
