Do you think you could make this mod compatible with the Bigger Artillery Mod? This is link:

The process should be nearly identical to making it compatible with the Light Artillery mod as you have already done. I tried it myself but it doesn't work because I don't really know what I'm doing. I really dig this mod, but right now my normal artillery sounds way louder and more badass than the Big Bertha which is twice its size. I mean just having the Big Bertha play the same audio as the normal currently does with your mod. It appears the volume can be adjusted in the data file so I can make it louder after.
If you could do this that would be awesome.
