You can combine the new parameters read from some user ini file into existing parameters in your Bootstrap.php as follows:
$newOptions = new Zend_Config_Ini(APPLICATION_PATH . '/configs/newoptions.ini');
$this->setOptions($newOptions->toArray());
However, if you just want to read the user file and access it through your application, I would recommend storing it in Zend_Registry:
$newOptions = new Zend_Config_Ini(APPLICATION_PATH . '/configs/newoptions.ini');
Zend_Registry::set('newoptions', $newOptions);
When they are in the registry, you can always get them (for example, in your actions) simply by calling the get method:
$newOptions = Zend_Registry::get('newoptions');
