To add to my comment earlier, what about building upon previous models? The content isn't 100% what your initiative is about, but "Persepolis "was a beautiful story and work of art about a girl/woman with guts in Iran.
This is a really great idea! It will provide excellent role models for women and girls.
One thought that I have is about product being free right from the start. Product that is completely free might be interpreted as worthless, even immediately. Perhaps you can stratify your offerings. The posters/signage/billboards/media placement would obviously be free for anyone to look at and enjoy. The individual pamphlets/booklets could be offered "for sale," maybe a short activity to promote the campaign. The idea is to make it "cost" something to get, but no money and "affordable" time. Hence, the comic books could be valued.
