But unfortunately, you can’t rename interfaces.
During your parsing you could assign each one to an environment variable such that, for instance, $lan contains the network card name of the LAN one, and $wan contains the network name of the one going to the Internet. Unfortunately, this would probably mean changing a lot of existing shellscripts, but it's doable.
