It will indeed conflict with v1.0 of my hull wetness mod. Go get v1.1 with compatibility issues revised to prevent that here:

Also, Vorkapitan, you don't need to include the *.GR2 main file in your mod as it wasn't in itself modified. Only the *.sim files should do, thus it will drastically reduce your mod zip file size from that 10Mb to just a bunch of few Kb
Especially handy since it will become quite a big file and a waste of resources when you'll include every other subs
