If its best possible dream team that can be then minus Bagration in Team Ukraine + Sanitarium and minus Ben + Miloradovich (Alice).
Plus you should delete Alessandro, Archangel and Flashkodr from Russian team and add Red, Eddie (Edward Kenway), Besha (he's latvian like Shogun, but used to play for old roster which had most russians, so it would be better to put him there).
And I don't really think that CCCP was worse than Jedis that years? We beat them in GFL and lost only to V75. (11-9). Plus we beat TFFO also that time.
