biome corrupting/purifying could likely be done with a variable stored in the region such as corruptionLevel that would be used to determine variation in foliage color from normal, how fertile the land is (maybe), etc.

You could also include an owningFaction variable that would determine what kind of NPCs would spawn there.

However this would require changing every single lotr biome, in fact splitting them into regions, and changing those. This would indeed be a long and monotonous task. While I believe it may be possible, and perhaps not too hard, it would still be a very long process.

Beyond it taking a long time, there are a few things that wouldn't work out that well. First, should something happen like isengard take over the shire there would be some bushfires, and browned grass, but the hobbit's homes would stay in very near mint condition, while the uruks wouldn't bother building any structures to live in or anything. On the same note, if gondor took nurn to free the poor "citizens" the only difference would be gondor soldiers policing the area making it seem as though the people of nurn are now slaves to gondor. Also would be if the moredain overtook the jungles, or isengard the shire, there would still just be farmhands that would be ticked off at them, and maybe run. The invading faction wouldn't stand for that, they would enslave the natives ASAP.

Now some ideas would be make structures for the invading faction spawn there, however in already explored chunks this wouldn't work, and in unexplored ones, if it was done in such a fashion, the invaders structures would remain past even when the area was reclaimed.

Let's see... ah, yes. The invader could bury the domination flag, then banner it. Really quite simple, and the area is permanently yours.
