Alternate R and J ending

If I can change the ending of the film Romeo and Juliet , I'll change the tragic and sad ending to a happy ending for all the protagonists. I'll change it to where the plan of Friar Lawrence to fake Juliet's death to work. What I'll do is make Friar Lawrence wait in the chamber with Juliet's body to await Romeo since he'll be expecting that Romeo will come after hearing the news of Juliet's fake death.
