Sinden doesn't work well with plug n play setups unless it's from a Batocera build, which Batocera natively will be the closest to plug n play you will get. Not the most optimal but good for a beginner to play some games. (Just need to get your own roms to add on to it). Your drive is tied with however it came when you bought it. Those scripts are tied to each emulator and if it's goes into Teknoparrot or American Laser Games those scripts are tied to, you will break your setup. Rule of thumb, when buying a prebuilt hard drive, don't mess with it, use it as intended. To your actual question, i run 3 instances of Launchbox (One for Main use, LG Setup and testing/misc use) Just have to rename your root launchbox folder something different than your Regular Launchbox folder (e.g. Launchbox LG). Also if you proceed to do what you suggested, create a backup folder for all your files in your paid drive. If case you do mess something up and can't reverse the issues, you can delete and start again with the backup folder. Good luck.
