Putting on my university professor hat for a moment, if you dont mind.
Looking at some of the suggestions, I'd gently remind everyone that the requirements are "scenically heavy", and many of the shows you've listed -- such as PIPPIN, SUNDAY IN THE PARK, and a few others -- fail under that category. The teacher here probably wants to see not only style but also how the student would organize the show from a logistical point of view... and while it's fun imagining DREAMGIRLS with its 27 scenes, that's an automatic indicator that it's to be a unit set show -- and therefore would have to be disqualified as not meeting the criteria.
It's one thing to suggests shows you *like*, but if they dont meet his assigment's requirements, they're not helping much.
That's really the problem with post-80s musicals (thinking in terms of the assignment): they're all written to exploit not only the rapidly expading thetre technology available but also in a more presentational style. The look is more fragmented and skeletal, rather than Meilziner's layer o layer of full stage drops and complicated flat work. And that's extended into revivals as well: look at the differences, for example, between the original GUYS AND DOLLS and Robin Wagner's retake for the last revival. Wagner had so many toys at his disposal that he could just about put anything on that stage and make it work. But when you're starting out as a designer, IMHO it's important to know what the limitations are so you can *then* find ways to circumvent them. Looking over the list of requirements for the assignment, it's pretty clear the teacher wants the students to understand the limitations of the pre-technology theatre so they can move on to the next step.
Just my guess, but I think it bears considering.
