Also, only US has hull class system with "DD", "CL", "BB", the other nation just call with name, thus, if you want to use code different from US systerm, it must not has similiar thing in US systerm like Fast Battlsship, because US don't use slow or fast battleship for diffrerent role, they just put stronger engine and it become "fast", thus FBB is foreign loan code, as same as PBB - Pocket Battleship of German, also US don't has FBB, PBB on the systerm, so it is accepted.

While, Armoured Aircraft Carriers also use by US, UK and the role, displacement just as same as standard carrier, so just CV in US systerm. If you want other code, you can creat new one for Armroued Aircraft, but not CVB, because CVB already use for Large Aircraft Carrier with ability co carry long range medium bomber, thus the role is different from standard cairrer., and their displacement also as twice as the standard. It will become a mess if real CVB are released.
