I’ve been looking into the code in the breadcrumb plugin to examine how this would be possible. This code obviously is able to retrieve the parent pages, and I imagine it’s just a matter of retrieving all the pages that don’t have children in the site and stuffing them into an array called $parents. I’m not sure how to translate what is here into what I am after yet though, but for anyone else wanting similar functionality I think this would be a good starting point.

function get_breadcrumb_page($breadcrumb, $params)
{
  global $wp_query;

  if ($wp_query->is_page)
  {
    $object = $wp_query->get_queried_object();

    // Parents.
    $parent_id  = $object->post_parent;
    $parents    = array();
    while ($parent_id)
    {
      $page       = get_page($parent_id);

      if ($params["link_none"])
        $parents[]  = get_the_title($page->ID);
      else
        $parents[]  = '<a href="'.get_permalink($page->ID).'" title="'.get_the_title($page->ID).'">'.get_the_title($page->ID).'</a>';

      $parent_id  = $page->post_parent;
    }

    // Parents are in reverse order.
    $parents    = array_reverse($parents);
    $breadcrumb = array_merge($breadcrumb, $parents);

    // Current page.
    if ((breadcrumb_is_paged() || $params["link_all"]) && !$params["link_none"])
      $breadcrumb[] = '<a href="'.get_permalink($object->ID).'" title="'.get_the_title($object->ID).'">'.get_the_title($object->ID).'</a>';
    else
      $breadcrumb[] = get_the_title($object->ID);
  }

  return $breadcrumb;
}
