I assume you are asking if they can have viable offspring, and the answer is no, probably not. The thing is that there are two systems of inheritance involved here, a natural one and a magical one. Centocutane have a heavily damaged natural system augmented by a magical system that did the damage in the first place, and Saratoans have a perfectly functional natural system and magical system which rely on each other mutually to make them work like they do.
The genes and spells have to match up in such a way that the child isn’t missing vital parts. Even Saratoans and humans produce a living child only once in centuries, and humans at least have all their genes intact (generally) and no magic system to compete with.
If both parties are missing the same natural system though, and the magic systems are completely different in ways that can’t be combined, the chances are slim to none that the combination will be functional.
It also doesn’t help that in Saratoans pregnancy is a more involved process. It doesn’t appear different in any external sense, but a big part of how Saratoans develop is a process governed by the mother’s body’s magic, which is why the only human/Saratoan hybrid to survive (Eli) had a Saratoan mother - it wouldn’t have worked with the parent’s species reversed. So the child also has to be functionally capable of surviving that process as well, or else the mother’s body could easily kill it.
Which is the long way of saying no, probably not.
