checkout/session setQuote

Question

I am working with a module that has a lot of hard-coded calls to Mage::getSingleton('checkout/session')->getQuote() I am trying to call it from Adminhtml and in stead of rewriting a huge chunk of the module, I thought I would set the checkout session quote to the quote stored in my object (which is valid). However when I type the code:

Mage::getSingleton('checkout/session') ->setQuote($this->getQuote()) ->save();

I get the following error:

Fatal error: Uncaught exception 'Exception' with message 'Serialization of 'Mage_Core_Model_Config_Element' is not allowed'

Is there a quick way to override the checkout/session's quote?

Normally if you want to load a quote from the admin you would use

/**
 * Retrieve quote object
 *
 * @return Mage_Sales_Model_Quote
 */
protected function _getQuote()
{
    return $this->_getSession()->getQuote();
}

/**
 * Retrieve session object
 *
 * @return Mage_Adminhtml_Model_Session_Quote
 */
protected function _getSession()
{
    return Mage::getSingleton('adminhtml/session_quote');
}

So if you know the quote id then you could try loading the quote

$this->_getSession()->clear();
$this->_getQuote()->setQuoteId($id)->setStoreId($store_id)->setIsActive(true)->load($id);
