On the brushes would be purity Kangaroo proof.
Call in an order that is 3 bristles thick in a 45-60°angle. Each row counter the next.this will give some stability and stiffness. Im gussing with there 250mm (~9") bristles. they would be your desired 6" length . maby do 5 of eachV and U .

For V
Dump the air into the front brakes/wheel wells. ( a low pressure zone). Best would be to make the end an air curtain th direct the air around the front wheel. Fill the finder tire gap with the brushes on the front 2/3.


U shape
The chin would be back behind the bumper on a gental curve out to the tyer ~ 1/3 in from the outer edge With out air curtains. With them iirc it would lind up with the out side of the tire creating a low presure high velocity on the front of the tire.

. Park a truck pointed into the wind take notice of the bow wake . Try to mimic this natural shape, as nature is pointing the parh of least reassurance.
Like kach22i did hear.

Thoughts I had what is goung to keep a kangaroo from sliding up the hood and coming through the windshield. A brush/ kangaroo garde made with airfoil shaped tubing. Adjust the angle of attack in loacal air( the loacal direction of air traval accounting for the bow wake . Not the direction of road travel. ) to move and accelerate the air in the direction most suitable for your shape. If dond right the Airfoils direction of lift will be forward. (Resulting in a negative drag coefficient?)

Maby run both stiles U in frontto air curtains at 3"deep and V at 6"deep continued filling of the turbulent low presure wheel well. Even add a secondary air curtains from the V at the back of the tyer.
