This is looking really good. I like the ideas ^_^ Russia depends on how far it goes. It probably won't have a border with Rome (probably some German or Slavic state(s)), but if it goes all expansionist like in OTL it will have one with China. So it's got three options - neutrality (for obvious reasons), join China (to avoid a battle in their far east, and possibly to take some stuff on the west front if any statelet is allied with Rome), or join Rome (to take some stuff from China). The older American nation would probably be Chinese. Couple of interesting thoughts to mention. 1 - the Chinese government would likely not sponsor wholesale colonization of America, odds are it'll be for personal or commercial gain. A lot of it would probably be like English colonization, peasants seeking an easier life in the New World. 2 - What would Japan's position on colonization be? Under Nobunaga, who knows, it might get in on it (if we save him from assassination); and under Hideyoshi they certainly would. An idea me and some friends had a while ago involved China being a counterpart to Spain (taking stuff from the natives (though likely not total conquest), but never really colonizing), and Japan being a counterpart to Britain (really getting in on colonization, and having an epic navy and a lot of overseas possessions in the 1800s).
