What if the Romani took over Rome

I dont mean this to be political, just crazy, because this is a site for crazy ideas, but Im reading a book right now where they talk about the right of return for Jews to Israel, because Jews have been ostracized all over the world. The Romani people have also been ostracized all over the world, so what about a right of return for the Romani people, to Rome?

Barring that the Romani people didn't come from Rome, this would have the advantage that it would give Italy another chance at world domination and be a controversial but beneficent sort of hard-to-argue-against Catholic sort of thing to do. They could start by taking over the Vatican, the new liberal pope could disband the centralized Catholic Church and distribute all of the top tier Catholics around the world to missionary feet-washing positions and allow the Vatican to become the worldwide Romani headquarters. Then the Romani could launch a movement to get everyone else to renounce ownership and start travelling, thus ending the centralized rental hierarchy of land ownership that is providing us with the bad model that all of the online companies are following, and introducing a little chaos into the world order that might fall out as a more distributed model.
