Thank you for asking this!! I've changed my mind, and am now gonna require that 3rd round submissions are .txt files, so that 1. it's easy for me to provide the .txts for everyone to access (especially the other collaborators, who likely have an interest in taking those files for their own purposes) and 2. so that the final collaborators don't have an expectation of a different kind of labor (i.e. layout and etc).
