Ideally, I would like to be able to assign the management device a RFC 1918 IP, have the actual server be on a different subnet altogether but use a shared port.
This isn't a good idea because of fate-sharing - you want your OOB management network to be isolated and bulletproof, and totally unaffected by any problems on the production side. You should use separate NICs, with separate cables, plugged into a separate physical network (unless you're using N7K switches with VDCs, in which case you can safely run the management network on a separate VDC on the same hardware, given the control- and management-plane isolation).
