It's a possibility. Looking at the idea of crucifixion historically, it would not be out of the question for Jesus to have been disposed of like most other victims of crucifixion. However, and this is coming from someone who subscribes to Crossan, I don not think this is the case for Jesus.
Jesus would not have been the only victim of crucifixion who was laid to rest in a tomb. There is another somewhat famous case (just google crucified man, and I'm sure it should pop up. I forget the persons name) of such a thing happening.
The key would be whether or not Jesus had followers or follower who were well connected or had money. The Gospels say yes. More so, Matthew tells us that there had been a tradition among some Jews who said the body of Jesus was stolen from the tomb. So we know the story is old enough for opposition to form and not just a denial of Jesus being placed in a tomb.
More so, the fact that women were said to have found the tomb empty seems to me quite important. Primarily because it is an embarrassing point. I see no reason to make up such a story considering how women were viewed in that time.
And really, a tomb never was necessary. A missing body wasnt necessary. He idea of resurrection needed neither.
