You could do it. I'm a Latter-day Saint (Mormon) and there is a group called "Leading Saints" https://leadingsaints.org/ that does 'Virtual Summits' since there are many (more) members of the Church outside of the 'Mormon corridor' (Utah, Idaho, Arizona ish areas) than there are in it.
You could reach out to Kurt Francom and ask him what mistakes they've made with their virtual summits to try and avoid and then apply a more tech-knowledgeable approach for a security virtual conference.
