Hey,
I tried that myself a little while back and found that one of the plugin files runs a checksum code against the weapons lua amongst others - I guess it's a plagiarism protection thing which one can't begrudge the authors of such a fine mod. Even if you tweak your custom weapons file to exactly match the file size of the original, the checksum still won't match and breaks the mod. With my limited coding knowlege, I tried to turn off the checksum checker but had no luck.
My memory is a bit foggy as to which file did what but in short, I hit a hard brick wall and gave up. Perhaps you might have more luck, would love to hear if you do find a workaround.
Cheers
