Not sure what you mean by being able to stream DEH; if you're talking about the movie, that disaster really shouldn't keep you from experiencing the very different show. I second the suggestions of Hadestown and Six, both of which are must-sees. Can't speak to Music Man, Paradise Square, Strange Loop, or Mr. Saturday Night, all of which I have tickets for on my own April/May trip (which also includes the three you already have set for yours), but I've heard good to great things about all of them. And while your post suggests you're more into musicals than plays, there are a lot of good or promising play options available (some of which are also on my schedule), including How I Learned to Drive, Hangmen, The Minutes, American Buffalo, Take Me Out, Birthday Candles, Plaza Suite, Potus, and The Skin of Our Teeth.
