Not particularly, to be honest. I don't see any particular reason why, if Christianity hadn't happened, any other religion would have risen to take its place. Without Christianity, I suspect that some cult based on northern European paganism would eventually have predominated, at least in Europe. The interesting question is whether Judaism and Islam would have developed differently without Christianity, and if so how - but that is almost impossible to answer. Yes, terrible "yoke" - apart from the aqueduct, sanitation, roads... in reality the Romans didn't really do much to Palestine either positive or negative. It wasn't like Ben Hur. Also, there aren't actually all that many prophecies about a Messiah in the Old Testament or in intertestamental Jewish literature. There were plenty of itinerant preachers, plenty of miracle-workers, and also plenty of rabble-rousers, some of whom led uprisings against the Romans and got squashed for their pains. And some of these did claim to be the Messiah. It is of course unlikely that Jesus ever did, although we can't really know for certain. No, it is pretty unlikely that Jesus claimed to be divine at all. As I said, there were plenty of such people. The most obvious example is John the Baptist, who at the time was very probably much more popular and better known than Jesus.
