Hi Clay,
It is possible. You can create a custom field (type text) with ID post_title to replace the default title. For default Post, use the code below to remove the default title
add_action( 'init', function () {
remove_post_type_support( 'post', 'title' );
} );
Then you can use the shortcode [rwmb_meta id='post_title'] to show the post title.
