You may be able to add a plain-text message with CSS alone, but anything more than that (like a clickable link or anything) would likely require some JavaScript hacks.

I can't say for sure, but personally, I would assume this goes against the Customization policy (keeping Wikia features in the same place), so I'm hesitant to suggest any code unless/until someone says it's okay to do 😯
