I'm sure there's a reason why this doesn't happen already, but honestly some people really need the extra time to filter through the reading lists before they get to a lecture or seminar meeting. Some people are slow readers and find studying these more complicated readings difficult. While reading every week is good practice for time management, there really should be an option to be able to start early and get ahead. This would give them more time to read generally around the subjects brought up in essential readings and therefore will be able to progress further in their studies.
Just an idea. And something that will definitely help me in the future if this happens.
