I don't think that a blower effect from the flywheels would change the volume of of transfer into the cylinder. All the pressure created that causes the transfer is from the piston descending down the cylinder. A squirrel cage fan works because it can draw in from it's center and blow out radially. There really is no center for the flywheels to draw in from, so how can it blow out? At best, I can see it creating turbulence in the crankcase cavity and that may help keep the fuel suspended in the air as well as stir it up a bit more.
I can also tell you that I have learned from my elders whom raced 2 stroke snowmobiles and dirt bikes in the 60's and 70's. They did all that they could to smooth every part involved in the crank case area. Polishing the cases internally, filling in the balancing holes in the flywheel with a light weight epoxy, polishing flywheels, polishing the connecting rods. All done in an effort to reduce parasitic drag on the air flow to maximize pumping efficiency.
