What is a good alternative ending essay of Romeo and Juliet for the play?

Romeo and Juliet could end in a variety of ways. Many would make sense. It would still be a tragedy if Romeo died while Juliet lived or vice versa. You could have an alternative ending in which Juliet is forced to marry Paris and Romeo leaves Verona a broken and lonely man. You could also have the play not end in tragedy and go the Disney route. Romeo and Juliet lived happily ever after. It is entirely up to you how you want an alternative ending to play out.
The question states that your response will be in an essay format. That is a bit unique because the source material is a play, and your alternative ending format is a prose essay. I'm not entirely sure what your essay has to contain, but I would begin by giving a generalization about how Shakespeare's play actually ends. Then I would narrate what your alternative ending would encompass. Finally, I would spend some time explaining why that alternative ending would work with the overall context of the play. I would also spend some time justifying why the alternative ending is a superior ending. Perhaps your new ending would resonate better with modern day audiences, or maybe you believe that your rewrite allows the play to be even more tragic.
