I don't expect the role quests to be crossovers from all the job stories. That may be confusing for people that have only leveled one job in a role etc.
I expect them to thematically tie into what the role is about on some level. But I think they'll be more creative than just teamups of npcs from a given role. They may even have a shared theme like the Virtues from SHB, that ties into the Endwalker storysomehow.
