Is it possible to put two differents malar/cheeks implants on top of eachother and fix them with screws? (Photo)

My middle face lacks bone structure and volume, my ps will adress it with extended orbital rim/malar implants, and because i want the apple-rounded cheeks he said he could put terino malar shells and fix the edge on top of the other implant. Also he said he can put all the implants through intra oral incision. Is all this possible? If not how to adress with implants my lack of under eyes volum and apple cheeks ? i don't want fat injections or HA i need bony structure but no custom made
