How to change inline creditor toolbar buttons in js file

i want to change inline ckeditor toolbar buttons on one condition like :

i tried it by 2 ways

1.on focus i tired to destroy existing editor and create new with following type of config.

if( $('#scheduled_email_filter_id').val() ) {

    CKEDITOR.inline( editorId,{
         toolbar    : 'Toolbar_One',
         extraPlugins : 'Plugin1,Plugin2,Plugin3,Plugin4'
      });
} else {
      CKEDITOR.inline( editorId,{
         toolbar    : 'Toolbar_Two',
         extraPlugins : 'Plugin1,Plugin2,Plugin3'

      });

} 

2. also i tired to fire event "configLoaded" on focus 

by editor.fire('configLoaded');

but both are not working is any one know other way to achive this .
