I can't support this claim at all.
Diesels are typically ~30% more efficient (fuel used per mile) than gasoline engines, right?
So how is there "not much to gain" from using a diesel with the same hybrid system?
I don't remember seeing a suggestion to take out the hybrid setup, just to use a diesel engine instead of gasoline... that would make the Prius ~30% more efficient on diesel.
EPA rating for the Prius Gasoline Hybrid is: 50C/49H
30% higher than 50mippigs is 65 mippigs... I'd rather have the latter, and that's the "we're not really going to try" EPA estimate.
