That's what I got from your description.  I lay claim to any witch/sorceress in the form of a man.  Just saying I like to bend the rules.  

In terms of the mixture of typesetting, I guess it would all depend on how confusing it would be.  I think having it in the present-day would be great.  We can tackle things like the evil mastermind behind the release of a certain virus.  We can have some mythical creature planning on melting the ice caps to flood the Earth.  Even small things like a detective would solve on a daily.
