Sounds completely reasonable to me.

Also thinking of a modified spoiler to grab some of the clean air over the roof and direct it downward over the glass area. I remember some of the early minivans used something similar to keep the rear glass free of dirt/snow...?

I feel that if this were something that were effective aero-wise, that we would be seeing it more on vehicles then we do. If your purpose is just solely to keep the snow off the rear, then it will probably help.

As for the snow clinging to the car after the rear wheels...? I'm not entirely sure I can explain that. Maybe the air coming off the trailing edge of the wheel? Another low pressure area?

Low Pressure area would be my guess as well.
