If the issue is an intake restriction then I would devise a flap that was closed when the supercharger was operating and otherwise open until the supercharger's pressure closed off the nonboosted pathway. A rocker flap that only required the preessure to exceed ambient pressure to change the charge pathway to through the supercharger.
But I still like the idea of a positive displacement supercharger that would replace the throttle plate, where the restriction was utilized for some electricity generation. It would not be much but you have to consider the duty cycle where the supercharger was actually providing pressure. In my case, I seldom see over 3500 in the Fiesta, even through a whole tank of fuel.
I think the electric supercharger has a future, when combined with an engine like the ecoboost with reduced displacement, so in my case the engine could be less displacement which means higher load for the same vehicle speed and better efficiency under all operational parameters.
It would also mean start-stop would not have to deal with cooking the oil in a normal turbo setup.
