FWIW I would not want any taller gearing in the differential. To me it feels just right as is.
Now that you mention it, towing our 4200 pound J-Liberty with our 2007 E350, it seems somewhat over-geared. So I can relate to your comment. Maybe it's better for fuel economy, but it doesn't feel quite right.
Not towing, the E350 gearing feels fine....actually perfect. We did average 10.6 mpg over the 5500 miles driven last trip without towing. With tow vehicle prior trip average over 4000 miles was 9.2 mpg.
