I have a hard time believing that anything will contain raspberries. But this sounds like it might work.
I don't know about their containment ability, but my grandmother used to grow currants at the feet of her raspberry canes, as they appreciated the shade. I know also that some people use comfrey in exactly the method you're describing, as a containment plant.
I would say try it. The rhubarb will also appreciate the shade. And then, if you keep your canes well-tended and you harvest strategically, your rhubarb harvest will indeed contain raspberries, at least when they're in season.
