Does SARPE have to be the primary operation or can SARPE and LeFort be performed during the same operation? (Photo)

I'm 29. I've class 3 and a bit narrow upper jaw. But I don’t suffer from any snoring or apnea. Doctor thought SARPE is not necessary. I use Damon braces. He said they could help that too. But I've aesthetic concerns about narrowness. To me SARPE and LeFort I are nearly the same things. So I wonder if palatal expansion can be performed during the maxillary advancement operation. Like not in couples weeks by expander but at once by separating the palate and screwing them in final position.
