releated products

[tomas.ch]

Hello,
I want to ask if there is any reasonable way to edit related products? Related products are generated in the file default_relatedproducts.php using the $ field-> display. Unfortunately, I don´t know about any way to edit this function so that I´m trying to deal with it by using php functions (regular expressions, explode, str_replace, etc.) to extracted at least some data from this function such as the title or the image. But there is problem with geting a short description and price. Price and short_desc aren´t in the $field. This field contain only a limited amount of data, but one of them is the product id. Do you think than there is possible way to getthe price and description of the product by using procust id? Or is there a simpler way than this crazy one that I´m using?
Thanks for any ideas
sorry for my very bad english

$product_model = VmModel::getModel('product');
$product = $product_model->getProduct($id,TRUE,TRUE,TRUE,$quantity);

//public function getProduct ($virtuemart_product_id = NULL, $front = TRUE, $withCalc = TRUE, $onlyPublished = TRUE, $quantity = 1,$customfields = TRUE)
