Took me a while to make a move, but today I finally tried to do something about it. I didn't know how to write in the proper wiki syntax so I had to study that first. I did some initial testing with the "PP7" page at first (I didn't first know about the "Playground" page where you can test the syntax, sorry for that).
If you take a look at the "Weapons" --> "PP7" page, you will see what I could come up with in a couple of hours. Nothing special, just a more readable page, although not as nice-looking (aestetic-wise) as the original page before its code got broken. All weapon data and descriptions are there as they were before, I didn't make any changes to them. Some links I removed (leading to the PKing Soup achievements, pages that don't even exist anymore), as well as some old code that became broken at some point (why the code got broken in the first place beats me).
If this work is to be continued, the pictures of the weapons are needed. Some of the pictures, like the one with the two PP7 pistols I used, are found here:
http://www.moddb.com/mods/goldeneye-source/images/pp7#imagebox. However, not all weapon images are found there, but I recognize that many of the colored weapon images used to be used in the weapon data pages. In fact, images for most of the weapons aren't there. I would need someone to provide me with links to all weapon images if I am to update all the weapon pages.
If I'm gonna do the updating work, I will be focusing to get the data out there, and not focus too much on the aestetic part (how the table boundaries should look like etc.), as I'm not that good with the wiki coding (yet).
