To Kamm or not to Kamm...that is the question

I have started my aerocap and the frame is done. It is changeable at this time and I have another question.

I have seen these Kammbacks on other vehicles. I assume they are to help get a cleaner air separation at the rear. With my cap being vertical and nearly flush with the tailgate (red line), could I benefit from adding something like this (green line) at the tail end of my cap? Or does the cap in general constitute a Kammback and maybe add nothing.

It was just a thought and wouldn't be all that hard to add if I would see any more benefit. Or if the benefit is too small maybe it's not worth doing?
