Except that Morrowind has a very successful compilation that actually works very well.
Not saying it would work for Skyrim, but just saying.
That is a rather new thing (the Overhaul). There was Balmora Expanded (or what it was called) before that, but that was years after release. For Oblivion, FCom didn't go all the way to provide a comprehensive installer, but it's essentially a similar thing, and it took some years to get there, as well.
So for Skyrim, there might be some compilation.
In 5 years' time, when things have settled down, clear favourites have been established, and many people have moved on.
