I think your point about showing up with solutions is the key. I think you can convince them of the need, but you have to respect the resources they have available.
My friend undertook a whole GT program for her children but that meant, planning the curriculum, the staffing, doing the fundraising. And it that was just for some pull out classes and projects.
Hence, I would look at the industry around you and see what kind of fundraising and support you might get there for pull out classes. Also, look at any museums or universities that might help with programs.
good luck,
