Oh, yes -- I tried your first method for "Hvetshran Wiki" and it did return over a dozen of the 20 Hvetshran wikis that exist. That's probably a lot less time-consuming than the methods I mentioned above (: The second method will indeed take a bit of time and effort, though seems very effective as well for wikis that don't have varying names.

Additionally I also thought that going to the Wikia Activity Monitor would work out for searching wikis as well, though that would limit it to the 5000 most active wikias there are, which international wikis unfortunately seldom fall under.
