Something similar was created by a man from Russia. There is a photo of the model on the link. karopka.ru/community/user/21616/?MODEL=538227

Word of warning, the huge Dora kits are so hugely flawed, it isn't even funny. So anyone into accuracy can pretty much forget about the kits out there. Presumably, the original drawings were burned, or is kept in a safe at some military institution or something I would think. I managed to recreate the Dora on drawings (work not completed), but I burned out on the project when I found out I had to buy a lathe machine. 🙂 A possible future project to finish.
