Considering the harm done to the economy by the creation of Utopia I'd suggest calling it the Bank Of BB.
I don't understand why the term Heaven was thought relevant to Utopia in any case. Its not relevant to the book and represents a misunderstanding as far as I can see. And of course, its ludicrous to ban religion from the forum and then have it in a league name. Not just ludicrous, but hypocritical also. I'd have thought that was reason enough to change it. I personally don't find it offensive, but I can see why some would.
If we're going to be serious, then in the book Utopia, from which the word comes, another land is known as Macarenses, which can be translated as Happy Land, and since reaching the pinnacle in your country should make you happy perhaps that could work as a League name. Though I'd have thought Division 1 would suffice.
