Reverse cephalic lateral crura trim?

Obviously once cartilage is cut out it is gone. I have watched videos of this maneuver done on YouTube. My question is can ear cartilage that is curved be used to replace where cartilage was trimmed? Can cadaver cartilage from a nose be used for this where the lateral crura was trimmed? Would it look fake? My nose tip was narrowed, I want my dorsal hump restored and bulbous round tip restored. I know I need an elite revision surgeon and in person consult. I want my old nose restored as best possible
