Most landscapes that need a GND with a 4/3 sensor are going to need one with a full frame anyways. Dynamic range has more to do with bit depth and raw capture than sensor size - a couple years ago, the DR of FF cameras was less than 4/3 sensors today...
A note on your article: don't be afraid you rough up your pro gear, it's made to take the abuse. Weight is a valid reason for leaving a D700 at home; "I might drop it!" isn't.
