THIS. was literally just about to post this request. It's a shame it looks like there's been no response for so long. If a modder who has worked with sound effects could even just roughly explain the process of extracting then replacing sounds from DS2 and 3 respectively I bet a rank layperson like myself could even do it. Anyway, one vote for this mod, and also agree about breathing new life and how good DS2's gameplay is (DS3 would be better but the lack of a proper poise system is weird).
