Since the Kamm follows the ideal shape, any deviation will increase drag. There is not much benefit to extending the roofline without dropping, as the entire concept of the extension is to return the displaced air back to it's original position with the minimum disruption. If straight back, you will be just moving the drag backwards without reducing it, at least that's my limited understanding.
