Were the nav to be styled to match the local community’s theme, that wouldn’t give any indication to the user that you can search for other content.

You could change the top so that "search all of Wikia" is more visible. It honestly seems like you're trying to create horrible design changes, and if you want more pageviews and clicks on your ads, being aesthetically pleasing will also help.
