It might be something that could work for a new game, but in the case of skyrim, I don't see any kind of paid mod system working. Skyrim has a very complex modding system, and a lot of skyrim mods have dependencies on other skyrim mods, so when you start putting any mods behind a paywall things get dicey real fast. It could only see this working in a game where mods are simple and standalone.
