MagicTigger on "site list similar to wp_get_archives"

hi, i have an archive page that shall show the last 25 articles.
so far, so good - with "wp_get_archives".

BUT, there are static sites that i want to list in the same list.
on first sight i said heureka, there is "wp_get_sites", but this function returns not what i wanted.

<h3>Die letzten 25 Beitr&auml;ge</h3>
            <ol>
                <?php wp_get_archives('type=postbypost&limit=25'); ?>
<?php wp_get_sites('public=1&limit=25'); ?>
            </ol>

i know there are some plugins doing nearly what i want, but its only nearly. :)

any ideas?

many thanks in advance.
