I've seen it done before. but the guy did it with the entire mod basically made NW with all the shit from L'Aigle. He had given it to one individual (Creators name isn't known) from the 32nd in EU. He made youtube videos with the mod for their regiment. However, He wouldn't give it out due to "He didn't know if the creator wanted others to have" Yeah ik doesn't make sense. Basically to do what you want takes effort. The way to do it is take all the files from each folder and you have to name them the same as they're named in NW to do the conversion. I'm working on doing it myself with the entire mod then making it public where anyone can have it. If you wanna do it with the musket sounds it's easy but with everything else like I said you have to sit there, and rename all the files to what they're called in Napoleonic Wars.
