route does not require a controller to be specified. If you omit the controller it will just load the specified page but you will have limited functionality.

No. This is not what directives are for. Quoting from the docs for directives:

What are Directives?

At a high level, directives are markers on a DOM element (such as an attribute, element name, or CSS class) that tell AngularJS's HTML compiler ($compile) to attach a specified behavior to that DOM element or even transform the DOM element and its children.

...and the docs for controllers:

Understanding Controllers

In Angular, a Controller is a JavaScript constructor function that is used to augment the Angular Scope.

When a Controller is attached to the DOM via the ng-controller directive, Angular will instantiate a new Controller object, using the specified Controller's constructor function. A new child scope will be available as an injectable parameter to the Controller's constructor function as $scope.

Use Controllers to:

  • Set up the initial state of the $scope object.
  • Add behavior to the $scope object.
