As I understand it you have to do this under certian rare conditions and if the event isn't prepared for then it won't work properly. One of those conditions is a proper Full Moon at a certain part of the year (March) only all within so long (an undetermined stretch of time) of the Wolf's death. The genetic compatibility is the only thing Cora would have going for her in a situation like that. I could of course be mistaken but I recall Peter's conciousness actually having a discussion about this with Lydia and Dr. Deaton mentioned something along these lines too. I could be mis-remembering though.
