Short Story Idea

I have decided that my short film will be based on William Shakespeare's 'Seven ages of man.' This poem is from Shakespeare's 'As you like it' and uin the peom shakesphere explains how life is split up in 7 parts; infancy, school boy, lover, soldier, justice pantaloon and second childishness and I plan to show these steps in my short film. I have stumbled onto a problem relating to the shortage of male actors so I plan to twist the original story to relate to a woman's life and her problems. e.g Instead of the woman being in the army her partner can be the soldier in Afghanistan. This idea relates to the modern problems of the world and of women.
