callback function from a module

In drupal 5.x

If I have a module1.module with one menu:
$items[] = array(
'path' => 'admin/settings/fields',
'title' => t('Fields'),
'callback' => 'drupal_get_form',
'callback arguments' => array('module1_field'),
'access' => user_access('administer fields'),
'type' => MENU_LOCAL_TASK,

and a
function module1_field(){
...
}

that create in the url site/admin/settings/fields a page with some fields.

Is possible to create one other module that in other url site/admin/mysettings
have the same page?
I think the problem is that the callback arguments must to point
at the function of the module1. Think in drupal 6.x ispossible but drupal 5.x?
