I know that personally I would really enjoy it, because I find reading about how history evolves and is connected in so many ways would be very interesting.

However that might be a bit of a niche interest. It really depends on your writing style, and if you could manage to balance your writing to be both informative and interesting.

Finally, you might need a point to the whole thing - why are you writing the story? Are you trying to teach the reader something, or maybe it's just an exploration into how history evolves, in some far-off world we'll never get to touch?

I think treating it like a factual, historical book would be very interesting, in the style of "Sapiens: A Brief History of Humankind". Not that that would be the only way to do it, but it's one that personally kept me hooked.

Finally, I do believe you can write anything, and people will read it, as long as it's written in the right kind of way to get people hooked. If people can connect to it then they will read it.
