anyone here want to guess how much light the whole starry night sky would then produce?

Are you talking only about light that is in the optical range when it gets to us? Are you counting the light that gets absorbed by dust and stellar interiors before it can get to us?
If that's what you're counting, I'd guess that it would be about as bright as a magnitude -2 or -3 star. So about one billionth as much light as we get from the sun.
