If Elesh Norn declared they were going to invade every plane, Jin-Gitaxias would have internally thought "what a stupid idea" and then talked her down to only invading 5 planes at a time. He would have suggested they start with those planes that are particularly rich in artifice and zombies, as those would be the most valuable assets in continuing their conquest. He would have proposed they start with just Innistrad, Amonkhet, Kaladesh, Alara and Dominaria. He would advise that with those planes under their control, they'd be better equipped to take on the others. He might even suggest Norn lead the invasion of Dominaria, as a treat.
