Would placing grafts on the sides of my nose minimize the appearance of indentations and dark contours? (photos)

After my rhinoplasty, my nasal tip is far too narrow for my round face. My surgeon sutured the top cartilages too closely together, which is why the sides of my nose tip were insufficiently supplied with blood, causing the skin to turn white and become heavily scarred. I also dislike the dark contour from the protruding cartilage (red circled area). Is it possible to put grafts in the sides so that this dark contour and the indentation disappear? How dangerous is this in terms of new scarring?
