RAM consumption for Nginx isn't that high, an HA instance may consumes <30MB RAM, see this link for more details.
For the port issue, what you can do is have a single Nginx instance running with privilege mode to bind in :80, :443. This way you still have process isolation and are covered in case someones exploit your web-server.
