Can I Make my Long Face Appear Shorter by Shortening my Nose and Chin or Possibly a Fat Graft?

I have a long face but i was wondering if there are things i can do to either make my face look more oval or square with good overall balance. My question is: can i shorten my nose and give myself more philtrum...to create a smaller looking midface. Further question: would shaving my chin slightly and adding a fat graft around my cheek and jaw help. I would really appreciate your opinions on this, and also suggestions on what you think would work well towards achiving my goals. .
