re: What about
I still don't think it's likely, but don't let that stop you. I think it was Arthur C. Clarke who once said, "The universe is not only queerer than we imagine, it's queerer than we're able to imagine."
In the vastness of the universe, your scenario could conceivably exist under some extreme conditions, it just seems unlikely to me. That doesn't necessarily mean it's impossible. Someone like Nick would be better to answer your question. Good luck.
