Since reducing the nose itself cannot be done with plastic surgery, I will only pick out the elements that can be done with plastic surgery
 
 - low nose tip and low columella (if the nose tip is raised, the columella also rises forward and the philtrum looks longer)
  - low starting point
  of the nose bridge - flatness
 between  the eyebrows - weak nose bridge hump (breaks the line of sight so that the nose doesn't look long)
  - thick upper lip and moderately narrow philtrum
  - moderately long and protruding mouth
  - moderate cheekbones and square jaw
  - low eyebrow position
 
Personally, I think these elements compensate for the long mid-face without making it stand out.
