Just a thought difool2,
You will prolly want to hold off until the release of the GWX 2.1 update. All campaign files in GWX 2.0 will be adjusted by 2.1.
Waiting a bit will save you a great deal of work.
As to whether or not there is too much in the way of shipping out at sea in GWX... best I can tell, GWX only represents a fraction of it. It is certainly a debatable matter.
The problem is that it is too easy to find since a few real life factors are not modelled into SH3.... For instance Enigma being broken and the Allies rerouting shipping well away from known U-boat locations.
Cheers.
