Multi-age elective advice needed

I’m teaching a multi-age elective Code Studio course for 1-5 graders. In the past I was able to manage students in two levels of the Courses 1-2 without too much difficulty. I’m struggling with the idea of having 5 different courses going at once using CSF Courses B-F, and I will not be able to do the projects for E & F. I’m leaning towards sticking with the old courses (1-4), but I’d love any feedback from others who have managed a similar situation and/or know the new A-F well enough to guide me. Thanks!
