Hey hey. This already looks quite good from a functional point of view. I think all the main aspects should be covered. What I thought was that this is a setup which really involved a lot of menu diving. Half of your modules have soo many functions and menus that it will not be a rack which is intuitive and quick to use and you will spend a lot of time searching in submenus. If you can life with this it is fine. If not I would think of maybe kicking out plaits since soundwise most of the sounds are included in the modes of beads and rings and some of the modules with screens and add a function generator (stages is highly recommended from my side).
Cheers
