Let's do a Wikipedia wide project, call it "Celebrate Women". There might be banners featuring either articles about women, or women editors. Featured articles during this period, of perhaps a year, would be biographies of women or even women played significant roles in.
Lists of articles which are needed or which need improvement could be drawn up and, of course, projects started.
By the way, work on the article "role model" is progressing and will eventually include a section on positive, as opposed to celebrity, role models, both male and female. I think there are quite a few resources, once you start looking for them in terms of lists of admired women, or men.
