@Anon: Not to mention, they have not only revealed more than once both in-show and out of it that Ruby and Yang are half-sisters. Changing that to 100% un-related would be....pretty much like an ass-pull. Plus, you're basically saying that they, both RT and Monty, have lied to us, more than once. Which is not how they do things, they either reveal something or not answer the question, but not lie.

And, like Phantom pointed out, the "potential for writing" would be far smaller than you thought.
