I don't think she'd want it. I know someone who interacts with her regularly at Stanford, and they say she's exactly where she wants to be. He said she gets offers from everywhere to go work/teach, but she considers Stanford home - she'd have to move to DC to be a Supreme. (And says very, very nice things about her.) (I've angled a couple of times to get invited to events she'd be at, but no dice.)

I would not be unhappy if Trump picked her and she accepted, but I'd be surprised, if she accepted, from all I've heard.
