I never liked some of the sounds in AOC, especially the war gong when attacked etc...I would rather be able to change them or even download new sounds uploaded and shared by other players. It would be really great to experience the game with fresh new sounds.

Hope its possible.

Yes it's possible, you can easily make a visual mod for it. (or private mod if you want)
