Allow user to edit weights from content overview

This is not really a feature request but more a howto style question:
Would it be possible to somehow hack the node.module in Drupal 4.6.2 so that you can change weights from the content overview page admin/node
It would be something like this (lines 909-919 Drupal 4.6.2 node.module):

  $header = array(NULL, t('Title'), t('Type'), t('Author'), t('Weight'), t('Status'), t('Operations')); //added t('Weight'),

  $destination = drupal_get_destination();
  while ($node = db_fetch_object($result)) {
    $rows[] = array(form_checkbox(NULL, 'nodes]['. $node->nid, 1, 0),
                    l($node->title, 'node/'. $node->nid) .' '. theme('mark', node_mark($node->nid, $node->changed)),
                    node_invoke($node, 'node_name'),
                    format_name($node),
                    l('weight', $node->weight, variable_get('weight_range', 20)), //I'm not sure how to pull the weights for the node and be able to change it like appears on node/add/story
                    ($node->status ? t('published') : t('not published')),
                    l(t('edit'), 'node/'. $node->nid .'/edit', array(), $destination));
  }
