Serious question:
You keep mentioning you do not want to lead an adaptation of a story that is not your culture. What is your culture? That probably will help us narrow down what you are willing to work with.
EDIT: As a note, I'm a multiracial AFAB asexual, so I'm very accustomed to having to work with the cultures of other people that are not my own. I will be cool with anything. Si a ti parece, acuerdo!
