LMFAO! I can not wait to see your comments about their relationship...
I'm typically against the zombie genre as well, but something called to me creatively. From previous reviews in some of my stories, I've had a few people who aren't into shifter stories read and were interested. Hopefully when I get around to ZitS, it'll be the same for you. I'm not sure of the changes I'd make involving the typical tropes, but I'm eager to dive in once I get some free time.
I know the story would be an incredibly "what-if" addition to this storyverse. The question is how much I would play with. All I have confirmed so far is the primary point of view would come from Thabo (pre-Cyrus name change).
