I think it would have been nice if any two, or even all three of the generals were siblings. It would have added a lot more drama to the story. How would Leo have resisted Celes's incarceration and planned execution if she were his sister? And sure, it's sad that Leo died because he was a cool guy, but it would be even sadder if he was a cool guy and Celes's brother. And imagine how much it would hurt Celes if she had to watch one of her brothers kill the other and then try to destroy everything.

I guess I really just want things to be hard on Celes.
