A Module Loader Question

I want to know if I can achieve one particular goal with any particular module loader. Let me tell you a story.

My Fantasy App

I work on a large client side JavaScript application for a company with a fremium business model. Let's call it Freely. Freely's free experience is composed of modules A, B and C in the application. Once the user hands over their credit card, they enter the paid experience, which is composed of modules B-Z.

Each of modules A-Z is roughly the same size, so the free experience requires roughly 1/9th of the entire codebase in order to function correctly. I don't want the client to need to download all of the modules becuase only 1/100th of all users will actually end up paying. (The conversion rate is another issue, but at Freely, we're more focused on other things).
