|I researched propeller wakes subject and I learned two things :
First , Blade wakes happens in to area , blade tip and blade hub.
Second, it depends to more the two spirals distance to get the lower the wake distortion at transition and far field area.
I AM NOT SURE but if we can use two blades , one deflects upward and other blade deflects the downward , we can comply with spiral distance rule.
Spirals are been viewed at water tank tests at marine propeller tests and tips draws a spriral que at rotation.
These are 2-3 and 4 bladed propeller spirals and wakes.
