Do you mean extending the alliance between Echelon 5 and the Jedi over towards the 'Nex Venators' as well? If so, then it wouldn't really happen unless the Galactic Empire were under control by an outside power (i.e. the Undying Sith Empire) or the current ruler was/is threatened (both in his postion of power, and bodily).

Though the Undying Sith Empire simply being a threat to the GE itself as a whole might do it also (invasion/conquest, etc.). Dunno what's happening to the GE in the RP, so I couldn't make a valid choice/decision, still, sounds like a good enough plan, just need a good enough reason.
