Seems like it might help, but I've got no numbers to back it up. There's so much turbulence under a truck it might not make a noticeable difference. The Jeep Cherokee XJ had a skidplate sort of like your drawing. I didn't keep track of mileage when I had mine.

With a live axle like the XJ, it would have to drop down really far to direct air under the axle cleanly, with the differential being quit low and bouncing around. IFS setups have more clearance and are easier to build something like that for.
