Scott/Ororo isn't one of the bigger ships, but it is a ship that's out there. There was an X-Men story where an alternate reality version of Ororo was married to Scott. There seemed to be potential hints during the period when Jean was dead, but before Scott met Maddie. It obviously never went anywhere and it very well may have been intended as a close friendship, but I do wonder if Claremont was considering a romance between them.
