This past weekend, I co-organized and co-hosted a virtual conference in number theory: https://people.math.sc.edu/thornef/pajamas.html https://people.math.sc.edu/thornef/pajamas.html I found it to be a very worthwhile experience. We had around 100 participants, around 50-60 at any given time. We had synchronous Zoom lectures with Q&A, "virtual coffee breaks", and a Discord forum for discussion. Not sure if I have any particular suggestions for your format; ours was rather tailored to academia and I don't have much experience outside that realm. But you're imagining what the experience would be like for attendees, which suggests that your conference would very likely be a success. You can see a blog post about a similar, but significantly larger, conference here: https://www.daniellitt.com/blog/2020/4/20/wagon-lessons-learned https://www.daniellitt.com/blog/2020/4/20/wagon-lessons-lear... I say do it. A lot of people are lonely and not getting enough interaction with others. Not sure I could give you any detailed advice, but I imagine that the experience could be very worthwhile.
