Groundhog Day: Now THAT I'd love to see. So many ballets nowadays are pretty much of repetitive and interchangeable, in essence anyway if not in detail, as were Bill Murray's days.
Napoleon and Josephine: You'd have to revise the story structure. Josephine's story is interesting in an upwardly-mobile Manon kind of way UNTIL she marries Napoleon. After that, she sits around a lot in Paris and Malmaison while he conquers much of Europe. I'd love to see the character dancing by Napoleon's grasping and very strange mother, brothers, and sisters. But Josephine?

What about the Bluebeard story? (Or -- if modern versions need something more familiar and "accessible" -- the Wives of Henry VIII?)
