Pretty certain of a Team Nagato victory here, mid diff at most, although I concede that it is slightly dependant on Nagato's condition. Taking Nagato as a fully mobile shinobi here, he could casually solo both A and Kakashi. Kakashi would be soloed by Nagato's summons, though the frogs could help if help is needed (though I doubt it would be). A can be soloed with Chibaku Tensei, which would also be the end of Kakashi if by fluke chance he survives a summon onslaught. Due to lack of info on Tobirama, it's difficult to see how he would fare in this duel. Edo Tensei is pretty much a non-factor considering it was imperfect and supposedly worse than Orochimaru's version. If Nidaime was taken out by 20 Elite Jounin, then he will certainly be defeated by Naruto's 15 KM clones; infact, that many probably won't be needed. BM Naruto simply has wayyy too much for the 3rd Raikage.
