I wouldn't recommend this approach.
Best if you just create another Plutonium shortcut with the following command line:
plutonium.exe -install-dir "C:\Plutonium-server"Like mine for example:
107274d5-403e-448a-af68-a05ad4a43cb0-image.png
and point your start_xx_server.bat file to the C:\Plutonium-server\ while keeping your game exe different.
