This would probably be considered a violation of the customization policy. Even if it isn't, it still isn't a good idea. The text used for that button is determined by the user's language. You see "Publish" because your language is set to English. If you set it to something else, you will see something else (ex. "Publier" for French, "Publicar" for Portuguese, and "保存本页" for Chinese). This is done so that, even if the wiki is not in the user's native language, the basic interface is. By changing the text, you are removing this capability; unless you are going to translate your custom text, perform identification of the user's language, and then select the appropriate translation. - Edit:

Now that I think about it, the poll button is a similar situation. So it probably isn't a good idea to do it there either. The exception would be if Wikia already approved your JS. However, applying similar logic, they probably won't.
