How to install only the autoload and laravel routes in a new project?

We are testing a new project for a high-traffic website (a few hundred, or thousands, of users per second) and wondered if there is any way to install only the route and autoload system for laravel. We will not need all the modules that come with it, initially. Some lighter version or some way to uninstall via composer which will not be used. In other words we need the minimum MVC configuration for this framework.
