Strip unnecessary packages from Installation ISO

I was going to download Matlab 2015b and redistribute it internally for installation on the company network, but since the downloader can't talk to our proxy server I'm forced to unpack the ginormous ISO file and distribute the contents of that instead. How do I know which files I can strip away to make it a more manageable size (Max ~1.5 GB) with only the core Matlab files and a few packages? Is there a Mathworks/3rd party tool that I can use to remove the files from the installation folder?

I'm looking to keep only these toolboxes: Fixed point toolbox, Matlab Coder, Matlab Compiler, Parallel Toolbox.
