New Story Title Question

[Maxwell Moon-Hoof]

I'm trying to make a good Fallout Equestria story that can probably be a movie or book, I have the setting fresh and ready it is a Film/story about a OC Pony of Mine that is a mail pony that has only one friend which is another OC Pony I created. Who live together in a normal and strange life inside a stable. However I was going to Make it start in a flash black where the Main Character (My OC Pony) is already in the wasteland drinking coffee with his new friends and tell the story from a narration point to where it begins in the OC Ponies head. The Question (sorry if i didn't get to the point) what do you think of this idea? and the title is Called "Fallout Equestria: Radiation Sunset" I want to know if anyone has this title? the reason why i ask i don't want to be chastised for stealing someones Title.
