Saga, the musical?

Man, Brian K. Vaughan is having a moment: first Runaways on Hulu is a success, and now there are rumors floating around that Lin-Manuel Miranda might, just possibly, one day adapt Vaughan's space-opera comic series Saga into a musical. I'll believe this when I see it (it sounds too expensive to produce for anyone apart from, like, HBO, and I'm not sure how they'd feel about making a musical, even one with Miranda's name on it), but it's an exciting idea to contemplate.
