I don't think it would be smart of Disney to do a film about any historical person that there are solid facts about. It's better to keep it to those who have meer mysterious lives, such as Cleopatra, Kazunomiya, of another non-European princess. There are many good records on most European royals, be they female of male, so people would freak out if Disney changed anything. However, in cultures where they didn't keep much historical record of women, it would be easier to piece together a creative and interesting movie while still basing everything upon pure fact.
Not that I'm against another European princess, I just don't think that having a historically based one, especially a figure as prominent as Queen Victoria, would be a smart verplaats on Disney's part.
