@DeadmantoonsFandom I have seen ideas and concepts similar to what you've described before and if the writer is good at writing, can turn out like a masterpiece. I would say go for it, but maybe add in something else as well to shake up that particular genre or fandom.
I would love to see something like this happen, but if this is your first work, I would suggest working on a short story first, then expanding into a major story. This shorter story could be anything but will give you a feel for how to write a longer one, what to do better next time etc...
I hope you found this helpful!
