It's my opinion that the flow is okay for this project.
You might,just for simplicity,build two simple C-pillar buttresses exactly like you've drawn,mounted parallel.Then install a flat shelf spoiler,dead level,which extends from the top rear of the buttresses forward to as close as you dare get to the backlight.
----------------------------------------------------------------------------
The buttresses will force the side flow to behave itself over the trunklid sides and the shelf will sculpt the attached-vortex which the air will just skip over as if it was a solid Kamm roofline.
The air captured under the shelf will just be a stagnant pool of air dragged along with the car.

She won't be glamorous but it's only three easy to build pieces joined and mounted.
If it is hinged at the rear with some sort of forward latch,it will flip up,allowing you to get into the trunk without removal.
