i have thought about this myself and i bet its very possible. the possible gains depend on how the cam(s) are setup up with the duration and slope. if a cams lobes are configured such that the pressure from springs remains somewhat equal throughout 360 degrees of the cam's rotation the gains will not be as profound. (warning the rest of the paragraph is just a train of thought and may or may not be of value) in a motor geared for fuel economy, even softer springs may be of more value because the duration of the cams would be less so less likely to maintain constant spring pressure around 360 degrees of the cam(s)...
i know that with stiffer valve springs fuel economy is lost, so i really dont know... hmmm... maybe i am just pessimistic today...
i think softer springs would be harder to find, but maybe lighter valves are fairly abundant....

That's true too. In that case, the gains would be solely from reduced friction on the lobes.
