HMVC / Package support to build a modular application

I've been looking at different frameworks for quite some time for a big project I intend to start next year. There are a number of options that might work and nette is currently on that list as it support most things I'm looking for (DI, Composer, Routing, MVC) but there's one thing I couldn't find.

The project we'd like to start on would have to be very modular. To achieve this, we'd need to be able to put routes and everything into modules/packages/plugins or whatever you want to call it.

What I'm looking for is a structure like this:

public/
	css/
	js/
	index.php
modules/
	module_base/
		controllers/
		models/
		views/
		bootstrap.php
   	module_fun/
		controllers/
		models/
		views/
		bootstrap.php

bootstrap.php would be the file which initializes the whole module and might look like this:

<?php

// register routes, services
$container->registerService('myModuleServer', ...);
$router->addRoute(new Route('module_base/human/<id>', 'Human:view'));

// apply database changes
if ($moduleVersionChanged) {
	$db = $container->getService('database');
	$dbMigrator = $container->getService('database_migrator');
	if ($up) {
		$dbMigrator->up(...);
	}
	if ($down) {
		$dbMigrator->down(...);
	}
}

It's of course just some ugly pseudo code but I think it show where I'd like to go.

Can anyone point me in the right direction? Thanks a lot!
