Has there been any experimentation with redirecting window/sunroof air to the rear?

By experimentation, I mean something like attaching a duct to a slightly open window or sunroof area and piping it to the rear of the car to help fill the low pressure air vacuum behind it.

Has it ever been done or is there any reason why it can't/shouldn't be done?
