The only mod I'd been interested in - up the movement speed and faster spell/skill special effects in fights - doesn't exist.
There are available game trainers that do this though they sort of flip the lever the other way. They are VERY fast like absurdly fast, which may be what you want especially on "trash" fights to just move on to the next area. I'd provide a link but trainers are in that gray area that is often frowned upon, a google search will easily find you what you are looking for I'm guessing.
