Question Partial Boattail/Kammback on a sedan?

I know there have been myriads of threads related to kammbacks and boattails for hatchbacks, but how about sedans? Could a partial boattail or kammback be implemented on a sedan as well, and would it have the same FE benefit? I'm considering doing a kammback on my Civic sedan and was wondering about the following templates (color code interpretations below the images):

The white indicates the kammback and the black indicates a possible partial boattail.

The blue and green indicate the pieces for the kammback, and the purple and red indicate the pieces for the lower part of the partial boattail.

Any thoughts on this? Location, possible FE gains, durability (coroplast w/ zipties, tape, and clamps)?

I know it would be better if the sides extended to the outside, but this would require taping to the exterior paint, and I'd rather not risk the car's paint job. I might have to relocate the license plate as well so it remains visible.

Any tips/suggestions welcome! Or if it's just a bad idea just let me know!
