Excellent Work! You and your students are fantastic.
I would not publish the 7/16 screw version without test building it first. You never know about the gotchas until you try. Unless there is an obvious benefit for it, that is a significant difference in cost.
I was thinking about the 480mm Tr8*8 or 8*12 integrated NEMA steppers available today. It seems that something like that would make an even simpler setup, but more limited in size.
