What did the Japanese classify her as, a BB or a BC? If they classified her as a BB, than there's nothing wrong with using that appellation. There's nothing wrong with qualifying that designation of course, but neither is it absolutely necessary. I have a pretty good reference on the size, speed, armament, and armor of all major combat types from WWI and WWII. I'll check and see what it says of the Hiei. I'm pretty sure it classifies her as a BB, but I'll compare her to other BB's and BC's.
In general, other factors besides armor thickness were considered when determining what class to put something in. The weaknesses inherent in WWI BC designs went beyond the relatively thin armor (as compared to main battery calibre). Also remember that the Washington Naval Treaty limited the size and capabilities of ships, particularly battleships. It is possible that under those restrictions the Japanese's definition of what qualified as a battleship where different than other nation's ideas. If she was a battleship by their standards (as constrained by the WNT), than correcting everyone who calls her a BB is nitpicking.
But to answer the main suggestion that started this thead, yes! Give us a BB or two. However, we need a real damage model to go with it in that case, better control (such as variable speed and the ability to take the helm directly), and decent fire-control (range finders up on the range-finding towers/superstructure, where they belong, and linked battery fire).

P.S. Just read Sixpence' link...very nice. Sounds like
Japan considered her a Battleship after her refit.
