Idea for a Story

Has anyone considered writing a (DEFINITELY ALTERNATE UNIVERSE for reasons I will get into) fiction where Georg is a transman? I have zero idea how that would work given the time period, which is why it would most likely have to be AU, where the time and place are changed. I just think it would be interesting to have the children be either adopted, or even artificial insem. via donor or one of Georg's Navy friends. The way Agatha dies might have to be changed? As in the disease, due to the time period because of the changing epidemics in time periods and all that. Max and Georg's relationship could be very interesting. Maybe they're both trans-guys or Max is cis and Georg is trans. I'd probably opt for the 2nd route, but my writing is trash, which is why I'm giving my idea to you people, who can actually write good, LOL. I think the dynamic between him and Maria could be interesting in the before she finds out and the after. Also, how would she find out? Would he tell her, or would she find some old documents or pictures in the attic of their home? Maybe the children know and it slips out during a conversation with them, or maybe she walks into the study thinking it's empty but he's giving himself his weekly Testosterone injection prompting the discussion. How would Maria react to that coming from a very religious background? Also, would Elsa even be in the picture? Maybe they're in a relationship, things aren't really working out, but they're trying to force it for various reasons. Maybe Elsa just is not equipped to deal with how Georg is as a person and perhaps he even has PTSD as a result as his Naval service and has episodes that so far only the house staff and Max know how to handle. Maria, coming from a convent where people frequently tend to the needs of the sick and needy, will have most likely seen this before and during one of his worst episodes in the middle of the night that wakes her up, she is able to soothe him. Maybe that's how their bond starts? She's able to help him at his worst; he starts to see her better qualities as opposed to her coming off as an annoyance. At some point, Georg will break things off with Elsa and propose to Maria. There could be a Gazebo thing here, but idk, maybe just a lake-side thing would be enough. Honeymoon ( ͡° ͜ʖ ͡°) in Paris and all that. I'm a trans-guy, so if anyone wants to write this and has questions about being a trans-guy, then feel free to ask me. I'm an open book and have no problem asking any and all questions, even the most personal.
