That looks interesting. I guess if you didn't want to have the tracks crossing each other you could have the two tracks on different levels. After the big discussion on derailments, I have decided to avoid turnouts and crossings on mainlines where avoidable and keep them in stations and sidings where the trains will run slowly. I should qualify this by saying this is because my preference is for fast express trains which I like to run at speed. I'm sure if you like to run your trains slowly then this would not be a problem.
