That's a really good idea; you would start with a fresh PMS every day!
I've noticed that most of the times, when I shut down the program (either its standalone application or the service), the process javaw32.exe stays running, and, for example, I can't delete the log files in the installation folder, so I'm assuming it's the PMS instance that's using it. So I go and kill it manually, and after that, I can delete the logs.
I tell you this because you might want to include this too
Good luck with your idea
