Yes. You spin up a bigger displacement, or turn the same displacement
faster. With 2 TDCs per revolution, per rotor, it would be a great
compressor.  NSU set a few speed records with a 26CC motor bike engine
supercharged with another rotary acting as a compressor. The rotary was
actually designed as a compressor and patented. Felix came across the
drawings and modified them to have the housings rotating to get pure rotary
motion. Todays engine is actually the original compressor layout.

Lynn,
On the idea of using one rotor as a boost for the others.  Wouldn't it
have to either be larger, or be geared to run faster?  If you wanted to
run 5lbs of boost, for instance, that is a 1/3rd increase in air
pressure from ambient.  You couldn't just run the exhaust from the front
rotor into the rear, because the two are pumping the same volume.  You'd
the the front rotor to be 1/3rd wider so that it would displace that
much more air.
