Having had the benefit of being able to think about this without a hangover (!) it's boot out of gob time! I would, therefore, like to apologise...shortening the rod will indeed increase the cylinder capacity but the CR (compression ratio) will also fall so the power increase (if any) might not be what you would expect...increasing the swept volume is really the way to go but of course you then have to use spacers etc. to ensure the piston at TDC clears the head and to maintain the correct CR.
