My group will return to roam the halls as Harry Potter characters: Harry, Ron, Hermione, Professor McGonagall, and the Portrait of the Fat Lady.
We're working on a Doctor Who group with a (scaled-down) TARDIS, weeping angel, Roman Rory, older Amy Pond (The Girl Who Waited version), and the 11th Doctor.
I doubt I'll have much time to work on it (let alone finish by next May) but I want a Steampunk version of mourning Queen Victoria.
Clothes make a statement. Costumes tell a story.
