Well, at least two of the other properties you named probably wouldn't play America; Elisabeth and Rudolf both relate largely to European royalty, and the sad fact is that most (not all, but most) Americans don’t like history lessons in their entertainment. Problem is, that's the crowd buying tickets these days. In the case of the former, the story is so rooted in European history and lore, and a historical figure that is so little-known in our country (Sissi was and is an icon in Europe, but here she's a mere curiosity at best, unlike, say, Queen Elizabeth I or Marie Antoinette), that I just don't think the general American public would buy it. (In the case of the latter, it's all that plus a Wildhorn score; Rudolf is basically Box Office Poison: The Musical as far as Broadway is concerned.)
Mozart might work, but we've already had Amadeus suck all the juice out of that lemon, I think, and it doesn't help that the show's structure basically apes that of Jesus Christ Superstar, lacking only an obvious Judas figure (oddly, the French Mozart musical sort of places Salieri in a similar position, and then utterly abandons any other resemblance).
