Submit for review (roles and capabilities)

Hello there, this is a great plugin!
I’m trying to include wordpress publishing workflow to these docs, some users should be able to create but not directly publish a document.
So far I haven’t found a way to hook up properly with the plugin, so I changed the plugin’s code ( only a little ?? ).
Taking small steps, the first approch I came up with was these two changes:

1 Prevent auto-publish:
file: buddypress-docs/includes/component.php:394

// Document Approbal Workflow | WIP
$post_status = 'pending';
if ( current_user_can( 'publish_posts' ) ) {
	$post_status = 'publish';
}

$this_doc = new BP_Docs_Query;
$result = $this_doc->save( array( 'post_status'  => $post_status ) );
$redirect_url = ( current_user_can( 'publish_posts' ) ) ? $result['redirect_url'] : trailingslashit( bp_get_root_domain() ) . bp_docs_get_docs_slug();
if ( !current_user_can( 'publish_posts' ) ) {
	$result['message'] = __( 'Document has been sent for review', 'bp-docs' );
}
bp_core_add_message( $result['message'], $result['type'] );
bp_core_redirect( trailingslashit( $redirect_url ) );

2 Notify the user
file: buddypress-docs/includes/templates/docs/docs-loop.php:7

<div class="<?php bp_docs_container_class(); ?>">
	<?php if ( ! did_action( 'template_notices' ) ) : ?>
		<!-- Workflow for document approbal ADDENDUM -->
		<?php do_action( 'template_notices' ) ?>
		<!-- END ADDENDUM -->
	<?php endif ?>

Ugly, since I’m working directly in the plugin’s code. Has anyone addressed this issue before? Sounds pretty reasonable.
Thanks for reading.
