Which is to say, he'd have to take a back seat at SpaceX (which is running at full speed; Carmack would have to try to get back up to speed in aerospace just to contribute, difficult by itself).

But they'll also pick up anyone with a proven ability of solving difficult engineering problems even from completely different disciplines. SpaceX is doing things that haven't been done before anywhere, thus the domain experience can only take you so far...
