I don't think giving your queen a 13 year lifespan over an hunch that it might get the coordinate to work is a good idea and it would kill Historia's character but Isayama already killed Armin's character so I wouldn't exclude it.

Annie was able to partialy control titans* and she's not of royal blood from what we know at the moment so there is no reason Eren can't do the same.

(*she called the titans to eat her titan in the forest, supposely led all of them into Wall Maria and attacked the left wing backed up with an horde of them; since Zeke can only control those that injested his spinal fluid the only possible explanation is that Annie did all three)
