You can request that, but I wouldn't recommend it. Google recognizes Fandom as a site with hundreds of thousands of wikis, so from an SEO perspective there's no need to add wiki to the URL. Plus, keyword stuffing (aka adding keywords, like "wiki," into key parts of the site) is generally frowned upon by Google.
