I would not say that a blower doesn't work at all. They do and did on 2-stroke Diesels. But I doubt that they work at crank-RPM unless they have a relatively huge diameter.
It would need some calculating (blowers can be calculated) before making the first chips.

The blowers on Detroit Diesels are positive displacement ( Roots type)
Large stationary 2-stroke Diesels(back up generators) start on their Roots blowers and run on turbo-chargers for better fuel economy.
