Maybe I can help by making Installer for major releases of your mod (maybe even patches, depends on my free time). It could contain uninstaller for easy remove/replace/reinstall and it could integrate in control panel for removal. You can check installers that I am making for ETS mods -
Example.
By the way, great job, especially for us that do not have lot of extra time to mess with the game files.
