You're missing the point—whether or not they possess (or can learn) those abilities in any form is irrelevant, because those abilities would become progressively diluted, perhaps to the point where they are no longer even noticeable. Assuming the ability to use Kido is a genetic trait, if an offspring of an Arrancar and a Shinigami can learn it, they should at least not be capable of using it as effectively (not considering hybrid vigor).

The reason I brought up heredity at all is because, in fact, it does apply to supernatural abilities in the world of Bleach, as evidenced by the Quincy.
