Have you ever seen a book called "Kung Fu for Girls"?
This is most likely WAY different than what you are going for, but I reccommend it as something to look at. It is a selection of situations and techniques that apply specifically to the young urban female, and is told through some great illustrations. It gives very basic SD instructions, usually glaringly obvious, such as what to do if a strange man on the train sits down next to you and grabs your thigh (grab the offending hand and bust him in the jaw) etc.
Like I said, I'm sure the content is much different than what you're working on, but the format is there and I honestly think it's much more effective, comprehensive and attractive than a complicated MA book.
Maybe give it a look if you get the chance.

And I'll def read your book when it comes out
