I agree that if there is serious precedent, people can vary the locale of the language from Wikia's own on a wikia - the Tardis Wiki is a good example. Its all "English" anyway. It fits into an umbrella of locales that largely have the same rules, grammar and origin - a fact that the Hollywood industry largely bases its import success on. This conversation is also feasible for the same reason :D

If we take a look at animated movies for example, the language is tagged as English because they do not use extreme accenting and voice acting is tailored to be universally geared. But characters will noticeably speak mildly different locales of English if the universe is set in another country.
