I've seen suggestions online that for the next series the identity of the Traitors should be kept secret from the audience so we can play along. Not sure if it would work?

I don't think that would work. It would mean we wouldn't get any Traitor tower scenes, nor how any of those recruited react whilst deciding. Additionally, sometimes Traitors are seen talking to each other during the day, which then probably couldn't be used, even if they were overheard by others. Then there's the murder in plain sight task.
