The thing is, Moria was begun, according to the timeline, on December 18, 2010, which was about two months after the server opened. At that time, it was the most prized build on the server. In fact, I saw an MCME Trailer from early 2011 (somewhere around there) and it was really just a Moria showcase

To add to the age of it, Moria has never been redone. Most other locations on the server have been redone at least one or two times, but none for Moria. Therefore, I would say that there is no question that Moria should be almost completely redone.
Personally, I think it would be cool to modify the render mechanics for that area with a plugin. We could build Moria on another map, then when you approach the Moria entrance on the main map, then it would load the chunks from the Moria map as you entered Moria. If there is other data the server needs to process before the teleport to the new map, maybe it could do that as you are walking up to the Moria gate. As you leave, it could do the same thing. If this is possible, it would make a seamless teleport from one map to another. I have no idea if this could work, but if it can, it'd be very cool.
