Can bimax achieve this jaw?

How can I surgically turn my mandible/chin into his? (how many MM of advancement of each jaw, reshaping advice on chin).

these are quite old pics and have lost some bodyfat since, but still have a poor submental region and undefined jaw. I'm not sure if length/size is as important as mandible shape here in terms of what makes this achievable.
