I think the major flaw in this theory is that Grisha and Zeke would have to be over 100 years old. Since that's how long Titans existed. Which, technically, is not a problem for the Grisha part of your theory as evidenced by Ymir. But then that leaves Zeke who, it's hard to tell without a color image, doesn't look too much older than Grisha if they're relatives. And we currently have no evidence to prove being a Titan Shifter slows down the aging process.

Other than that, I do feel like Grisha was on his side for a while. So I feel that pretty much everything past this: "he rebelled" seems completely plausible.

Also, I think you could have edited your original post. :p
