This would allow reduced spoke count per discussion above as wheel deflection would be closer to the ground and not as prevalent at the top of the wheel near the brake pads.

The knock on some carbon aero wheels made by Rob was...to control their displacement...they don't flex much...you need more spokes. So why not simply reduce section modulus of a deep carbon aero section rim so you can reduce spoke count? Seems like win win.
