The problem with HTTPS is that it doesn't support 4th level domains (or at least certificate authorities aren't issuing such certificates), so  wouldn't really be possible.

4th level subdomains aren't an issue (their current certificate covers, for example). I dare say the issue for Wikia is that a wildcard can only be used in a single left-most level (so  wouldn't be possible), meaning their certificate (at least with the current URL structure) would have to contain individually every wiki subdomain that has an interlanguage version.
