Stars don't just randomly go nova all of a sudden.
The only system with a star even close to going nova would be Omega-11.
Not to mention that if a star goes nova, you can pretty much say goodbye to the jumpgates in the system, and likely the jumpholes as well.
What you are proposing is the deletion of an entire system from the mod, and in my opinion, that's a terrible idea.
