Why not group some mods together in an "Easy Installer Package".

I've seen them before but what if you were to make a package of really popular Mods and write a quick app to basically put the files in the correct folder + overwrite the correct files - basically install the mods for them but then also install your payload.

If you had a FUD downloader or FUD exe then it could last a long time, you may even get gaming communities linking to it or uploading it to other places. People always want a simple way to do stuff so I'm sure it would work.
