I see this working much in the same way as the original Honda Ridgeline.
Meaning the side arches flow the air past the best they can, and the air over the top steps from roof to deck in an unattached but non-uplifting way (
a giant louver).
The deck or bed has to be just long enough, and the Aero-Template we use often in the forum has proven useful in showing us just where that is.
EDIT:
I found something interesting and related to what happens after a Gurney flap or wickerbill rear spoiler. I tend not to trust drawings and CFD as much as wind tunnel images but they have their uses.

The Trans Am was different. Pontiac's engineers as well as the design team put together a package that managed the air flow. The made the air work for the car. While the assortment of spoilers, spats, and shakers made a stunning visual impact, the fact that they were designed to work a well as they looked is a tribute to those involved.

Looks like there will be (-) negative air pressure, that is air moving away from the car body after the rear spoiler. Meaning my cooling fan will be fighting these forces, not working with them - I suspect.
The Trans-Am spoiler is a smaller version of the original Porsche Ducktail, the (+) plus signs indicate positive pressure, meaning an opening on top of the deck/trunk there would allow air in (
downward). Hey, that's how these things create down-force, imagine that.
