I don't really know, but the pd car I drove with a lightweight flywheel (don't know how light) was very not smooth at idle, of course, the car may have had other issues.

Edit: this site has a decent theory on the fe increase http://www.murmini.com/articles/2007/04/01/dmf
essentially the vibration dampening of the flywheel allows lower speed operation (higher gear) and thus a fuel economy boost. Which I suppose would be of extra benifit with a super tall 6th.
