Several good points have already been brought up, pointing out problems with this project. Here's my 2 cents:
1. You say that you want to teach them wristlocks so that they don't have to resort to striking - aren't you forgetting that atemi is an important part of aikido? You may have heard the saying "strike with every technique". The strike is a vital part of the technique, necessary to unbalance the opponent enough that the lock/throw/whatever may be applied. Do you really think the bully/whoever is just going to stand there and let you put him in a wristlock? I think it's more likely that he'd be hitting you.
2. What is going to be more of a problem, getting a black eye from getting punched, or a broken wrist?
3. The way you call it a "dance" makes me very cautious. Real fighting is NOT dancing, and attempting to "dance" your way to victory could lead to getting yourself hurt.
