Old world in New (age of sigmar world)??

Now that the transition is almost complete, and that lovely little bridge between AOS and the old world is almost complete .. I wonder what we can do as a community to keep that original spirit alive?? I'm still happy at the mentions of disspossed ect. And I really hope they lean into the "old world in new world" aspect as much as they can in lore. Maybe .. if we are lucky even give us nice legends rules as well!! But now I'm wondering how the community could keep that spirit alive? What if there was a whole mini-narrative game of "Warhammer old world," with all the same rules and units but given new lore by us the players?? It's neat thinking of these little conflicts and histories being played out by say, Empire, Cathay, or Bretonnia type civilizations and societies within the free cities. And their fighting say, beastmen or old-style orcs who have yet to join the ironjaws in the ghur badlands!

So what do you say?? Let's make some homebrews!! It's a concept I'm super obsessed about and I wonder what you guys think as well.
