Hi Daan, thanks for getting in touch!
Neat idea. While coming up with an exact way to do this would require custom development that is outside what we can support here in the forums, I think it would be possible.
Would you need to change the post format for Organizers? Perhaps adding a custom field for a video to the post type (via Advanced Custom Fields or something similar) would do the trick so you could attached a video to the post and then modify the loop for the organizer archive to display those videos. That might be another way to accomplish it.
Sorry I don;t have more of a concrete solution, but I hope this at least gets you headed in the right direction!
Cheers,
Geoff
