The Largest Jewish Expo coming up? Let’s create one?

I’m just wondering from a Jewish pride perspective and from a unity perspective. Is there a Jewish conference that brings together under One roof as many people that would like to gather any night simply because we are Jews. I’m looking for an event that has everyone there Orthodox traditional conservative reform anybody that is considered Jewish. I’m wondering if there is an event that exists and if not would there be room to create such an event?
