The idea can work like that. There is only so much others can offer you from an outline. The real test would be when you start writing it. You should get a feel as you go along whether it is working along the lines you want. If you're not sure you can try getting a beta reader to take a lot at it or publicly posting it (here or somewhere else) and canvassing opinions.
In the opening post you say this is something you want to do and I don't want to discourage that. So I think you so go ahead and see what happens.
