I think the knack is going to be to get a SMPS regulator to have feedback from the input rather than ouput as the "logic" is reversed, if the feedback pin detects a large volatge it will restrict the output and so the input will go higher (straight up to max) if the input in under voltage it will just increase output and bring it down firther. I suppose some extra clever circuitry could reverse the logic..
