Adding a rib graft on top of existing one (dorsum)?

Had revision the graft looks really good. Want to know if i can have another graft on top of this one. Its a doraum rib graft and i want another thinner layered graft on top of this one to get a pyramid shape bridge. I also would like it to be curvy to get more 3 dimensiomal prominence In between dyebrows area. Just a small and thin graft will be a game changer for my face im sure of it. If possible.
