Honestly, not really. Even in the earliest gospel (Mark), after women enter Jesus' tomb, an angel says

"Do not be alarmed; you are looking for Jesus of Nazareth, who was crucified. He has been raised; he is not here."

And the earliest sources that we have -- the epistles of Paul -- are permeated with references to Jesus' resurrection.

The only thing that's been hypothesized is that the earliest Christians originally did not believe that Jesus underwent bodily resurrection, and that they instead believed that his body really did remain dead (wherever it had ended up), and that it was just his spirit that was "exalted to heaven." But, again, this was just hypothetical, and doesn't enjoy wide scholarly support; and the only texts that we have are insistent on resurrection.
