It could be interesting!
That said: Connections to industry figures (producers, general managers, theatre owners, nonprofit leaders, other lawyers, etc.) to interview them and get further takes will be a key to your success. To be totally honest, if you don't have a wealth of experience working in entertainment law (and, specifically, Broadway law), your work might be met with skepticism by the people who make shows happen, since theatre law can be a thorny subject. And scooping stories before the Forbes guys or Michael Riedel or Philip Boroff will be important in getting your name out there!
