There is no historical basis for your argument regarding the NT Gospel writers not being the actual author, nor Paul being the author of the majority of the 13 NT books he wrote.
Have you read any work on the subject? I will refer you to L. Michael White on the issue of the Pauline Epistles. Even wikipedia has an accurate article on it. There is no doubt that some of the Epistles were written after Paul died. There is no doubt some of them were not written by Paul, and this can be seen by how they were written. Here is some preliminary reading that will help you

As for the Gospels, they never suggest who they were written by. The Titles were added at a later date, which we know because the earliest references we have to them do not have the titles. We have the records showing just how the titles came about. We even have debates on who the authors truly are, such as in the case of the Gospel of John. History shows that we do not know who wrote the Gospels.
Your explanation regarding the impact of the resurrection is weak, at best. Christianity would have never taken off in Jeruselum, Rome and other parts of the world if people realized that Christ's body was either stolen, ravaged by dogs or buried in another tomb. It's just not plausible in light of the history
Actually it is very plausible. They were in a very different time period. They did not have communication such as we do today. Plus, Jesus really wasn't that important during that time. He was just one more failed messiah. So it was not a stretch to assume that a myth sprouted up about Jesus (one that a population was already predisposed to believe) and that no one could really check.
Jesus was dead, so they had to create an explanation for that. The Messiah was never suppose to be resurrected. As soon as he died he was a failure. So his followers made an explanation of why he didn't fail.
I've already communicated. The whole theory of hallucination is an old argument that has already been disputed by psychologists who have studied this issue. Over 500 people were documented to encounter Jesus over a period of a number of days (I Corinthians 15). The likelihood that all of these folks were hallucinating due to grief is ridiculous. As I've stated before, even skeptics are running out of arguments and beginning to accept the authenticity and historical basis for the New Testament. You're on the wrong side of history in your assessment.
Can you say exaggeration? And I'm not talking about hallucinations. I'm talking about a phenomenon that is highly attested to. One that people still see occur today.
The fact is, the majority of scholars accept that the New Testament is not historically accurate. I have no idea who you've been reading, but you are not familiar with the majority of the scholarship going on.
