I support the concept... however only if in RVSM/MNPS airspace and no need to do 2 or 3 nautical miles... 1 mile is enough... I fly from South America to Europe, and often tempted to change the last digit of longitude to get an offset... to the right...

We have triple INS (LTN-92) with 2 GPS updating, in our old 747-200s, so it is still time consuming to enter such corrected data without errors...

Hi BelArgUSA your post intrigues me....do you have to manually enter offset waypoints ?? Only have experience of of -400 so not familiar with your FMS fit.
