1.) What if, when the Moon Kingdom fell under Queen Beryl, there were survivors? What would their lives be like now? How would they react, knowing the Moon Princess is once again alive and well?
2.) The Senshi go to such lengths keeping their identities secret, what if everybody found out - and nobody cared?
3.) What if Usagi dies during the creation of Crystal Tokyo? (Chibi-Usa can be born already.)
4.) Friends and Family are the most important things to Usagi, right? So what if Naru, her oldest friend, demands that Usagi tell her what shes been doing or she won't be her friend anymore? In a public place.
5.) Usagi's pregnant, still in High School, and her parents kick her out. To top it all off, some astronauts landing on the moon's surface find the ruined Moon Palace. They find the Archives, which are magically updated when necessary, and learn the Senshi's true identities, Princess and Soldiers.
