I was working on a project much the same as that, and it fell through due to the business side of things. However, in the process, something else came up, so I can say that a book in that vein is in the process written by a professional writer working in conjunction with a well-known traceur. It has been accepted by several publishers, so just give it some time. I personally have some reservations about this project, but once it gets out in the open and on sale, then it opens the doorway for a book-buying market and I can get back to work on my own project.
This said, I hate the idea of tutorials in books as much as I hate the idea of video tutorials, website tutorials, and whatnot. In that regard, I wouldn't want to support something like that.. As for it being possible.. yes, it's possible, but the market is SO small right now that you probably won't have any agent willing to back you up on it.
