Well, you might have to make the straight longer, for example, to stop it overlapping. That wouldn't be a problem anyway since an F1 car would do the lap so quickly the races would be too short.
Maybe if the start straight was much longer, and the approach to hammerhead was too it wouldn't cross?
Or perhaps some one could do something a la suzuka, where it crosses over - put in a tunnel. It wouldn't be ideal but it should work.
