I recently came across this mod for Fallout 3 and I like the concept of it.

Unfortunately, he didn't make a version for New Vegas and it doesn't work if I simply copy it over into the New Vegas GECK. It uses FOSE and I guess he's using some commands that aren't compatible with NVSE. And I can't figure out how to get it to work in this game, nor can I figure out how to come up with my own version. The script he's using is this, with a couple of changes made by me:

If someone could take a look at this mod and figure out how to get it to work in New Vegas, I'd greatly appreciate it.
