As long as it doesn't violate the terms of use, isn't incredibly taxing on the servers, and doesn't expose users to risk by importing "bad" external resources, it will likely be approved

Wikia cops won't cops after you because you can't really deploy any site-wide script without their permission anyway. See [1].

Although for scripts that were pre-approved, whenever you make a change on them Staff can remove the offending code, and make whatever depended on it stop working.
