Ahh, no, a plugin can do it. There's a filter you can use to force the
walker, "wp_nav_menu_args".

Rather a long way to go though. And it doesn't allow for multiple
plugins creating different types of menu items, since only one walker
can be used.

BTW, in your example, it would actually make more sense for
Custom_Walker_Nav_Menu to extend Walker_Nav_Menu. Then you could
override just the start_el function, leaving the rest alone.
