No, it wouldn't work for the entire series but I think they could get away with doing it for the first 2-3 episodes so we don't see who Claudia picks or who she is talking too, and don't see their identities until the second murder. That could give the series a bit of week one hype.

Similarly if there is a recruit towards the end perhaps that could be kept secret too, but think it might be harder to not show the Traitors discussions at that stage than at the beginning, where it could soon be addressed in a flashback.
