I was trying to accomplish something similar. Here is how I did it.

My PHP is rusty so if you spot any improvements please do let me know.

I wanted to populate my post title to combine two custom fields: first-name and last-name

function custom_field_value_as_title( $value, $post_id, $field ) {
	global $_POST;
	// vars

	$new_title_first_name = get_field('first-name', $post_id);
	$new_title_last_name = get_field('last-name', $post_id);
    $new_title = "$new_title_last_name, $new_title_first_name";
	//$new_slug = sanitize_title( $new_title );

    $result = 

	// update post
	// http://codex.wordpress.org/Function_Reference/wp_update_post
	  $my_post = array(
      'ID'         => $post_id,
      'post_title' => $new_title,
	  'post_name'  => $post_id //originally $new_slug
  );

// Update the post into the database
  wp_update_post( $my_post );
}

add_filter('acf/update_value', 'custom_field_value_as_title', 10, 3);

The result in the post title is last-name, first-name. For example: “Obama, Barack”
