Arad - the Axis tanks we have at the moment are easily beaten for speed by the much faster T34, so on larger maps like Orel or even BDJ. the T34 would easily get to the cap zones first, and hold them long before the Axis could get there.
Some people may like that, but i prefer to have cap zones where both teams have an equal chance of getting to and capping at the same time. Arad would be just such a map although i still think the T34 would win the race, at least the Axis would have a chance of preventing them from capping, whereas in BDJ. the Allies with the faster tank, would already be there waiting.
Whatever map got converted would need to take into account that the T34 is a good bit faster than the Panzer, and the maps would have to be balanced by perhaps moving the Axis spawns closer to the cap zones.
I would include Ogledow,Barashka,Bonderarevo,Kryukovo,Mannikala,Rakowice or Hedgehog, but the question was about tank maps, and not combined arms maps.
I don't really care if the map is historically accurate or not, its the gameplay thats important.
