An RZ with any lens on it is hardly "elegant" doing cliff-hanging on top of a tripod in vertical mode . In fact, that is the entire point of having a rotating back. But of course, you are correct in that it will fix the orientation problem. To the best of my knowledge the lens barrel rotates. I'd be extremely surprised if it doesn't. There is no use in having a shift lens that only shifts horizontally.
