Aero wizards - what do you see as the plusses/minuses of these two?
Here are my poorly educated guesses:
Blue line is intended to be horizontal. Would allow a fairly clean view out the rear window. I think I prefer this version but consider the purple line one also.
Purple line would add downforce?? And I believe generating that downforce creates its own additional amount of drag? Or are the added downforce and drag very small due to relatively low pressure in the area just above the trunk lid?

I'm not an aero-wizard like aerohead, but I think this is good. I would also employ the blue-line solution. Along California98Civic's comment, here is an example for a hatchback that is similar to an XR4TI spoiler, albiet not a biplane (cosworth?!?!?!?) :
The blue-line solution could be a custom spoiler or maybe an adaption of an existing adjustable spoiler.
Here's another example that fits the streamline template (but extends beyond the bumper) :
