What most RR ideas suffer from though is the fact that people tend to have these ideas and don't intend on planning/running it themselves & want others to do it for them. So if you really want to run with this idea

and if you can wrangle together a group of people you think could help run/plan the RR with you, as well as compose a list of things you'd need pertaining to content & dev work, AND come up with (internally) a roadmap for how day 1, day 2, etc. will pan out, you'll likely get a bite.
This goes to anyone who has RR ideas as well. Can't outsource the work of organizing/planning it, you gotta put in the work. Your idea, your rodeo.
