Comment (by westonruter):

 I think what is being requested here is actually already possible. In the
 context of a control, you can access the preview's current URL and update
 the preview's URL via the associated `setting`, and the setting's
 `preview` value:

 {{{
 wp.customize.controlConstructor.foo = wp.customize.Control.extend( {
         ready: function() {
                 var url, control = this;

                 // Example: get the current URL
                 url = control.getPreviewUrl();

                 // Example: set URL of preview to homepage
                 control.setPreviewUrl( location.protocol + '//' +
 location.host );
         },

         getPreviewUrl: function () {
                 return this.setting.previewer.previewUrl();
         },

         setPreviewUrl: function ( url ) {
                 this.setting.previewer.previewUrl( url );
         }
 } );
 }}}
