As much as I complained about the original Lords of Shadow, I'd be willing to 100% it all over again if they add new music, playable characters, costumes and that kind of stuff.
The first thing I would get rid of is the battle music. Let the ambience track keep playing, so we can feel a sense of continuity on the stage, and not that feeling of "now I'm exploring, now I'm fighting, now I'm exploring again".
That became more evident in Mirror of Fate, but it was present in LoS already.
