Do you have any compressor maps or empirical data to support that?  I would 
like to see your data and test methodology. I am not sure that changing the 
blade tip shape is going to make as much if a difference as reducing 
backside leakage will. Changing the blade tip geometry will mostly just 
change the blower timing slightly adding more inlet and exit dwell time 
perhaps allow a small improvement.  I don't see huge improvements.

Positive displacement compressors are inherently much less efficient than 
centrifugal.
