A crazy but interesting(?) brainchild

Soooo, this is relevant to nothing in particular, but you know those franchises for Monster/Ever After High, which features Universal monsters and fairy tale characters in a high school setting? I was dwelling on that today, and a lightbulb sort of went off in my head, like, "hey, what if there was something like that with magical girls?". I mean, think about it, you've got the Sailor Senshi, Pretty Cure, Magic Knights, Mermaid Princesses, Mew Mews, Puella Magi, Love Angels, majokko, etc. and their villains attending high school together. Can you imagine what a chaotic extravaganza that would be?
