They would have been Christian. Look at the original Christian congregations. They were majorly made up of Jews, had the majority of Jews accepted Jesus, then their would have been more Christians in those first congregations.
However, that also opens up the question of... IF the Jews accepted Jesus, could he still have been the Messiah? Without his death, he was no more than a man, he wasn't the Messiah. And had he been accepted Jesus would not have been killed... So it's a circle of questioning which has no definitive answer.
As for the holocaust... The many of those forced in to camps and killed were NOT practicing Jews. They were Christians. It was the Nazis drive for "cultural purity" that would have still killed them off the same way. It had little to do with Religious Purity, although it is fact that other religious groups and systems were also targeted, it was their Israelite bloodline which doomed most of them.
