As I mentioned elswhere on SubSim I have used C. Gibs directions successfully through 1 full war. This was on a vanilla 1.4 install, running beside Commander. Note that this is fun for some things (limited time, trying tactics,etc.) and is NO where near the fun of GWX (imho). I do not know if this will work with GWX and have no desire to be the first to try it....
@Respensus: With the above caveat on my installation, and a suggestion to OF COURSE back up your files first, I have 7-zipped the relevant, modified files from my installation. Even zipped they come to a little more than 3mb. PM me if you are still interested and I'll try to figure how to get them to you.

Lots of fish = burning BB, sinking bogue carrier, sinking Illustrious, and misc. merchants sunk. Using limited time kept my wife happy!
Merry Christmas!
