Just after thinking, let's say a Supreme Court judge had to be chosen in due time - I know he's a Marmite guy in these parts - but Sessions would be a prime candidate, wouldn't he? If he wanted such a life sentence, that is (not sure I'd regard such a role as a welcome promotion)
But anyway…., seems like he'd be a good choice and has already proven his 'by the book' credentials to the 'ire' of President Trump.
