It's the net effect that matters. If a device has lower additional drag itself, but results in less overall drag reduction, that's not as useful as a device that has higher additional drag, but results in more overall drag reduction.

It would be of little use for that, for a couple of reasons:
- The hood-to-windshield transition is a low-to-high pressure transition. Flow doesn't separate in those transitions.
- If it did create more attachment and reduce the thickness of the boundary layer (neverminding #1 above), that would put the wipers in stronger flow, increasing drag.
