The rear looks a fair bit like my V50 wagon.
While the sides slope inward, they do so too fast.
I've wondered what VGs or AirTabs would do if they were used to make the air follow these fast curves better.
Airtabs and VGs are meant and shown to better "bend" the airflow - though at the expense of drag. So the benefit of bending the air must be made bigger than the loss caused by the drag ... if possible at all.
Why not try it while you've got them anyway ?
They can be re-used when adding new double-sided tape.

* the kamm-back extension on the rear window...easy to think of...harder to do...once made a set of louvers out of wood and alum for a rear window and used RTV to glue them to the glass....held several years. Problem might be the lip there?

Make the top flush with the lip / spoiler ?
I wonder wether it'd be OK to just put a Kammback on the glass alone, leaving the side-mounted taillights free.
Using lexan on a light frame, it'd hardly be visible.
Sure, it'd mean a side-step for the air coming from the sides.
If the Kammback is short, that air will blow by - won't help, but won't harm either..
If it's longer, that air could re-attach, however briefly.
But you'd still get the benefit of the extended roofline.
