如何显示wordpress帖子而不是404页面？

Question

I have an interesting task. I've wrote custom 404 handler for wordpress and extracted an URL. Than, after doing some logic I've got a wordpress post ID that I need to display instead of 404 page.

How can I display a wordpress post page instead of 404 page? The only thing I can think of is do

 echo wp_remote_fopen(....<post permalink>...);

But is there any alternative way to do that? Thanks

I was not able to do this by rewriting template's 404.php. And also I think that is would very template-depended. Instead I've managed to display a post by using template_redirect action. The code of plugin function looks like this:

    function func_404_redirect($query){
        global $wp_query;
        $post = get_post(2);
        $wp_query->queried_object = $post;
        $wp_query->is_single = true;
        $wp_query->is_404 = false;
        $wp_query->queried_object_id = $post->ID;
        $wp_query->post_count = 1;
        $wp_query->current_post=-1;
        $wp_query->posts = array($post);
    }
    add_filter('template_redirect','func_404_redirect');
