Taking the red line off 7th also probably helps car traffic flow north/south as there will be less train traffic.

A tunnel was wisely built under city hall when it was built in the 80s, but that's it. The rest would be very costly, which is probably why it has always been deferred in favour of new lines and extensions.
I agree with the benefits you mention though. Having the red line below 8th and the blue line on the existing 7th Ave tracks would isolate issues to one line or the other, and it would also allow for longer trains under 8th, and perhaps most importantly, increased frequency and efficiency.
But it wouldn't be cheap, that's for sure. I would imagine that it would become more of a priority after the green line is built, or in practical terms, decades from now!
