I don't understand why you want to go with Stits if you aren't going to do a lot of scale detailing. If the goal is, as you said, just to get it covered and in the air as quickly as possible, you won't see many of the benefits of using a fabric system. Do the plane in pre painted Solartex and shoot a coat of clear on it, then paint the stripe down the side and put the decals on. You can have that all done in the time it'll take just to apply the fabric with the Stits system. And Solartex does hold up fairly well. Yes, it will need to be reshrunk from time to time, and it will eventually start to come loose at the seams. But for a practical everyday flyer, it's the way to go.
