My recovery model is going to empower the addict, and get rid of any religious/spiritual nonsense, and use science and the scientific method to figure out why each person uses, and how best to correct it. I also will not allow people going for court to get a paper signed. You either want to be there, or you don't go.
I agree with the idea that we are not powerless over our addictions. We are actually quite willful, but instead of exerting our will in a positive direction, we chose a negative. Think about the steps we would go through in active addiction to use. Is this not powerful? Is it not driven? Are we not so cunning in order to maintain a habit? We are actually very powerful and dynamic people. Most addicts I have met have been incredibly talented in some way, or are very intelligent. I will not allow an imaginary deity to take credit for mine, and others achievements. It adds a certain mysticism to addicting that actually makes it harder for people to stop. Saying you need god to fix this is turning a health issue into a moral issue, which I believe just muddies the waters.
I am still working on the recovery model, but I have the bare bones. There are levels. First level is detox and mental health. Second level is coping, and learning the skills needed to stay clean, third level is working to correct your financial, legal, and interpersonal problems. Fourth level is teaching the other levels to people. There is no need for a sponsor because everyone helps each other. It is tasked to everyone that is farther along to help the newcomers. There will be a few heads to each meeting, and those people will decide if you are ready to start the next area of learning.
I also want to start a few detoxes that are based around tapering rather than cold turkey. Cold turkey is incredibly dangerous for quite a few addictions.
