I know for us, this is a tough time of year for the team trying to do anything in the school. We are starting our off season of outreach, etc., but almost all of the in-school team stuff should be finishing up in the next 10 days or less.
The students have a lot of demands placed on them with end of the year testing, projects, finals.
The teachers have those same demands on them and those demands step it up a notch in taking priority plus other demands as well.
The administration has those same demands on them plus the administrative things for future as you noted.

Graduation looms.

So, as an opinion, I would say this is not a prime time for starting a team or seeing that it would be a priority from the viewpoint of the administration or the teachers. For one thing exhaustion plays in here. Many people who work in education are counting the days until school's end and look forward to somewhat of a rest from the schedule/demands. (I realize that schools keep different schedules everywhere so I'm going with what is happening with our school here in Austin right now.)

I've also looked at some of the activities that you have listed and those do not have to be done in the classroom environment or the shop. Many principals take some time off during the summer but do keep somewhat of a schedule. You could stop by the school office and speak with the person who will/would know the principal's schedule then and see if a time could be worked out to meet again to help start the team when things aren't so hectic and time so demanding in other areas.

And I agree about finding sponsors now and during the summer. A lot of groundwork could be done that would benefit the start up of a team. Good luck with this.
