Multilingualpress & Posts 2 Posts Plugin

Hey,
I’m using the multilingualpress Plugin. Our Website is a little bit complex, we have different Post-Types and these Post-Types got different connections among each others. For connect the different Post-Types we use the Posts 2 Posts.
Both Plugins work really well.
But now I have a little porblem an d I hope someone can help me.
When I translate the german Post to the English, I want to get the setted connections in the english post too.
Can I add the connections in the Mlp_Translatable_Post_Data.php? Is it possible, that it works like this? Where I have to implement the Connections in the MultilingualPress?

public function save($post_id, WP_Post $post) {

		if ( ! $this->is_valid_save_request( $post ) ) {
			return;
		}

		$post_id = $this->get_real_post_id( $post_id );

		$this->save_context = array(
			'source_blog'    => get_current_blog_id(),
			'source_post'    => $post,
			'real_post_type' => $this->get_real_post_type( $post ),
			'real_post_id'   => $post_id,
		);

		// Get the post
		$post_data = get_post( $post_id, ARRAY_A );
		$post_meta = $this->get_post_meta_to_transfer();

		// Get the post connections
        $post_connection = p2p_get_meta( $post_id, 'type', true);

		/** This filter is documented in inc/advanced-translator/Mlp_Advanced_Translator_Data.php */
		$post_data = apply_filters( 'mlp_pre_save_post', $post_data, $this->save_context );
		if ( ! $post_data || ! is_array( $post_data ) ) {
			return;
		}

		$file     = $path = '';
		$fileinfo = array();

		// Check for thumbnail
		if ( current_theme_supports( 'post-thumbnails' ) ) {
			$thumb_id = get_post_thumbnail_id( $post_id );
			if ( 0 < $thumb_id ) {
				$path     = wp_upload_dir();
				$file     = get_post_meta( $thumb_id, '_wp_attached_file', true );
				$fileinfo = pathinfo( $file );
				include_once( ABSPATH . 'wp-admin/includes/image.php' ); //including the attachment function
			}
		}
		// Create the post array
		$new_post = array(
			'post_title'   => $post_data['post_title'],
			'post_content' => $post_data['post_content'],
			'post_status'  => 'publish',
			'post_author'  => $post_data['post_author'],
			'post_excerpt' => $post_data['post_excerpt'],
			'post_date'    => $post_data['post_date'],
			'post_type'    => $post_data['post_type'],
            'connected_type' => $post_connection ['connected_type'],
            'connected_items' => $post_connection ['connected_items'],
            // Create the connection part of the array
           // 'p2p_id' => $post_connection['post_connection'],

		);

I hope someone can help me!
Thanks in advance!
