This map is currently underway, with the help of a friend. It is unknown at this time exactly how long it will take, but the idea is to completely and acurately recreate a major section of the Big Shell from Metal Gear Solid 2. I plan to give major credit in an obvious way to Konami for being just plan awesome, so hopefully if ever they see the map they won't come smashing my door down. :P
Anyway, I don't think they'll get mad about a tribute from a big fan to one of the greatest series of games ever made.
More info to come soon, and screens!
