Don't worry whiteking, I am not offended. I would think that some modders may feel uneasy however if you change some of the files of the mod without asking or crediting. It is similar to a booster (some may disagree), perhaps not for the voice file change, but the _m file change, since some of the files within were modified and some were left intact. I don't think you should delete the sounds from the pack, but if any of the files were modified from mods, I believe credit for the modder would be good (like you have done in your edited post). Also, perhaps version number or date of the mod when they were modified since any update to the mod may need a new update to these _m voice files.
