If you feel an event is worthwhile at the convention, please feel free to step up to run it and submit the event as such, or as a panel (once submissions are open). Events at most conventions, including Zenkaikon, are all fan run. For us to run requested events, staff would still need to find someone to run it. Volunteering to run a panel/event takes a lot of the leg work out of trying to arrange requested events through others and then the event is more likely to happen.
Also, I would just like to point out that the video you linked really didn't have anything involved that pertained to your request (other than footage of the audience while they were seating). Including a description of what the event is, what they were doing, and linking a video that actually had the event running will help staff narrow down figuring out what this particular event is.
