Hey technically it is possible but it’s pain in the ass. I did it with Bain (deeper darker voice) for briefings and story questlines. But it’s not possible to get them alive ingame for me right now because the soundbank file does not contain them and stream will not be played idk why. The other part was the search and editing over 400 wav files (but I found a way to bulk edit waves) and there are still Bain voice waves at other folders with over 2-3k wave files so to answer your question, it’s not worth it to do this
