Rear edge you could bend to about 60 degree to meet the rear edge of the vehicle vertically or attach a metal bracket. 3mm abs migth also be sturdy enough, but I quess 5mm is safer bet
- on the rear edge of the trunk you make 90 degree angle bracket where you have sliding slots where you can adjust the angle. Based on internet side pictures you will need about 150mm adjustment in heigth
- Sides you need to block with clear pvs contruction plastic etc
- Then the measuring pots on the center line of that abs and also to to the vertical side of the tail.
- It should automatically form tapering spline shape which is optimal and wanted.
With this you can see and show what kind of roofline rear shape brings the lowest drag if I have understood correctly how those pressure sensors could be used. I am mainly interested to see if your claims on the "template" are proven false. Construction itself is really easy to make and does not necessary require any drilling to body if test speeds are kept reasonable. That is what I would test if I had that kind of change available.
What do you think?

You can easily do that test for yourself - no pressure testing needed. Just measure changes in total drag using the throttle stop technique.
