 Yes, I can share a code I created that can simulate that Twenty Fourteen
 theme had a Calendar widget in the sidebar-1 Sidebar before...

 {{{#!php

 $template_my = 'twentyfourteen';

 $theme_installed = get_option( $template_my . '_theme_installed', false );

 if ( ! (bool) $theme_installed ) {

         $sidebars_widgets = array(
                 'wp_inactive_widgets' => array(),
                 'sidebar-1' => array(
                         'calendar-2'
                 ),
                 'sidebar-2' => array(),
                 'sidebar-3' => array(),
         );

         set_theme_mod( 'sidebars_widgets', array( 'time' => time(), 'data'
 => $sidebars_widgets ) );

         $calendar_widget = array(
                 '2' => array(
                         'title' => ''
                 ),
                 '_multiwidget' => 1
         );

         update_option( 'widget_calendar', $calendar_widget );

         update_option( $template_my . '_theme_installed', true );
 }
 }}}


 So you can add this code to functions.php file of the Twenty Fourteen
 theme.
 To test this you need to:
 1. Go to themes page
 2. Click Live Preview for Twenty Fourteen theme (You will see the Calendar
 widget there in the sidebar)
 3. Click Save & Publish
 4. When you go after that to the widgets.php page the Calendar widget is
 not in the Sidebar anymore.

 Expected to see it there :(

 Hope this helps.
