I do not believe the stages themselves will be modules in Q. The core scripts will be. The additions on top of the core scripts that make up the stages are likely present. But not the stages themselves.
Saint corrected me below. Goes to show you even the best make mistakes.
Even so, keep in mind the multi-stage concept exists to adequately prepare you for the later stages. Jumping to a later stage before you are ready may have the opposite effect (or no effect).
Same goes for Q. It will likely allow you to create subs that are so heavy they give your subconscious indigestion. Don’t neglect your foundational development.
