My advice for this flipped model relates to Physics and Mathematics where it is problem based and we encourage the students to learn from each other. There are elements of this way of teaching that need to be flexible or evolve. For example: first year classes can be one hundred flipped, no new content delivered in class. By third year and honours where the concepts are more complex - there needs to be a mix of teaching approaches. While there is still content before the class time, there is a need to reinforce that knowledge by having conversations about that material in class.
Be prepared for a large-scale effort initially, this will be rewarded with a much smaller time taken for updates each year. Be prepared for a deep dive and slow going over of material.
There is always a central focus of classes being student led and go at the pace they deem necessary. Maybe you cover less of the bespoke content but give the students an opportunity for a deeper understanding and how to teach themselves.
You need buy-in from everyone involved in teaching and leading the education effort.
