No, this isn't possible. Wikia's wiki creation policy doesn't allow for wikis to be privately editable - they must be public. As you said, it's really easy to undo changes someone else has made - you can do it by one click with the revert button in most cases. If you ever get into any difficulty - we'll be able to sort it out here.
