I should note that the snow was only brushed off the front windshield and hood, the roof snow and tonneau cover snow was left virgin prior to driving off.

That's some great real world experimentation right there. I reckon with the spoiler pointed down 10 degrees and some buttress type fairings on the side it could really reduce the wake you're seeing on there. Of course you probably won't get the extra downforce of your current spoiler but you'd get gas savings! There's a thread somewhere of a Toyota Sienna with the side fairings. I'm not even going to attempt finding it.
