I would say yes, but it will effect *all* your gears.

Here is my gear ratio comparison :

Dividing ratios : 0.730 / 0.605 = 1.2066 => ~21% reduction in RPMs

Here is your final drive comparison :
Dividing ratios : 4.08 / 3.54 = 1.1524 => ~15% reduction in RPMs

I don't know if I would want that. For me, my "ace in the hole" is my lower gears.

But, if I wasn't in an urban environment, maybe I would have a different POV.
