Cool idea, I would agree with @bee_stevenson – find one school, and get a pilot underway. That would be your fastest method to both find a potential trail ‘customer’, get end-user feedback (students) and shake out the various collaborators you will need to make something work. By focusing on something as clear as a pilot with one partner, all the small things and partners you need will become clear to you just by going through the process and you can hunt them down as you go.
