If it allows airflow to reattach, and then produces a clean detatchment over the smaller area of the back of the car (rather than having the combined area of the back of the trunk and rear window under detatched flow), then it should help.

I guess this is why A-B-A is so important. Too many non-linear effects to accurately predict, even with some pretty serious computing power.

Fortunately, a flat coroplast spoiler would be easy to make and tape to the trunk for testing.
