I would say your chances of being successful here are somewhere around 0%.
Clearly you have never heard of the NWA "Bump" program. as that was exactly what they allowed. Even with their close partners, at the time being CO and DL.
DL does it too, to an extent. You have to have been ticketed on DL stock, with a return flight on another carrier in order to do it though.
