Nothing hard with this recipe: Simply paste the following code on your single.php and page.php, where you want the author name to be displayed.

<?php $author = get_post_meta($post->ID, "guest-author", true);
if ($author != "") {
    echo $author;
} else {
    the_author();
}  ?>

Once done, you just have to create a custom field named guest-author and type your custom title as a value.
