I know this is now ancient, but I've just started on something about a month ago, about when I had the idea, and could find no evidence that the basic idea of anything like it has been made, in any medium. So a plot outline turned into a summary, which became story, and now it looks like a full draft of act 1 will end up around 30 pages.
It's a story involving the Salem Witch Trials, and a couple real witches who just happened to be living in the area when they started, and they know not one of the accused are anywhere close.
