Magento get Wishlistitem from Product

Question

public function addItem(Mage_Wishlist_Model_Item $item)
{

    $superAttributes = Mage::app()->getRequest()->getParam('super_attribute');
    if ($item instanceof Mage_Wishlist_Model_Item && isset($superAttributes)) {
        $simpleItem = Mage::getModel('catalog/product_type_configurable')->getProductByAttributes($superAttributes, $item->getProduct());
    }

    return parent::addItem($simpleItem);
}

Now my problem is that i want to call the parent function which needs to receive an Mage_Wishlist_Model_Item not a Mage_Catalog_Model_Product

MyCustom_Wishlist_Model_Wishlist extends Mage_Wishlist_Model_Wishlist

How can i get the wishlistitem for the Product $simpleItem

public function addItem(Mage_Wishlist_Model_Item $item)
{
    $superAttributes = Mage::app()->getRequest()->getParam('super_attribute');
    if ($item instanceof Mage_Wishlist_Model_Item && isset($superAttributes)) {
        $product = Mage::getModel('catalog/product_type_configurable')->getProductByAttributes($superAttributes, $item->getProduct());
        $item = Mage::getModel('wishlist/item');
        $storeId = $product->hasWishlistStoreId() ? $product->getWishlistStoreId() : $this->getStore()->getId();
        $qty = 1;

        $item->setProductId($product->getId())
            ->setWishlistId($this->getId())
            ->setAddedAt(now())
            ->setStoreId($storeId)
            ->setOptions($product->getCustomOptions())
            ->setProduct($product)
            ->setQty($qty)
            ->save();
    }

    return parent::addItem($item);
}

This works for me now but i didn't figure out how to set the $qty yet
