Yes, that is along the lines of my thinking, getting the wing into better airflow upon braking by using the brake fans in a low pressure area, and then letting air stream rise ever so slightly above (?) the wing when fans turn off.
Not that I'm rule bound, but it might get me under the wire as not being a bonafide active movable aero device, until the rules change.
Here is a likely candidate for fan control, mounted within drivers reach.
