It seems to me that I remember that on the Avia forum there was mention of having a Tiger II as Trophy tank and it was pondered.I am not sure if anything ever came out of it.
Personally I think it's not very realistic since the Soviets never used the Tiger II ( only 492 were made) as it was too heavy, too difficult to maintain and they had plenty of their own tanks at that time and except for the Panzer IV and Panther . I would like to see more Beutepanzers on the German side including KV-1, T34-42, T-70 , T-26 and even a single JS-2 or T34-85. I think the Soviet side could use Stugs III Fs or Gs and may be Jagdpanzers IV and less variant of the Tiger I than we currently have in the ME.
I found the "trophy mod" thread on Sukhoi.ru. It provides the download for about 20 trophy tanks. Unfortunately when you try to unpack it, it says "unexpected end of archive". The installation leads to "corrupted" file message... Too bad, has a lot of USSR and German trophy tanks.
