Is the only way adding localized wordlist to hack diceware.module?

Hello,

To have a French wordlist put in the wordlists folder to be used by the module, I only found altering the diceware_block_configure() function as this:

  $form['diceware_wordfile'] = array(
    '#type' => 'select',
    '#title' => t('Language:'),
    '#default_value' => variable_get('diceware_wordfile', 'en'),
    '#options' => array(
      'de' => t('German'),
      'en' => t('English'),
      'fr' => t('French'),
    ),

Is there a cleaner way to do so?
