OK (question about restrictor plate)

I've read about cooler vs hotter air for intakes and it makes sense. I have also read that an engine is most efficient at closer to wide open, for less pumping loss due to to throttle plate. Now, if this is the case, could you not restrict how much air goes past the throttle plate, like Nascar 'plate racing', to where your car does indeed make less power and you are spending more time at deeper throttle?

Or would the restricted throttle opening take place of the close butterfly and result in the same mpg or worse?
