    i try to stay below 200mOhms on inductors.
    i don't have a choice on LED bins, that's why i'm going to all this trouble.

    I don't see any reason that shouldn't work. You lose some efficiency and overhead voltage switching the FET reverse polarity protection to diode. In this application I think that's not a problem, so schottky diodes are probably better than the FET solution; cheaper, smaller, and work a bit better, though the latter is probably insignificant.
