By doing anything you mean butchering their already established lore? As IF they did something wrong? Sir, there IS something wrong.
In your opinion. It's their lore to change as they will. You can't tell a creator how to handle what /they/ created. Go make you our book or game if you dislike it. But it's an insult.
And, mods are fan creations. Feel free to do what you want with them. But, they aren't canon, cause they weren't made by Bethesda. Personally I wouldn't use them.
If you dislike the game so much, and how they handled their creation, then do what you will with mods.
But, the game is good how it is by itself.
