We're no where near you, but I like the idea. My son loves being on stage and acting; I've noticed that acting works out well for a lot of kids with ASD, but I suspect there are many that would find actually trying out for a regular production to be a little out-putting, so what you are offering could be a nice little foot-in-the-water. Main thing I'm worried about is if you'll have enough concentration of need and location, but that you won't know if you don't put it out there.
