Doubtful, but I'm sure there are those that it may have cast doubts into their faith or at least reconsiderations, so it's still good that they can offer considerable academic evidence against the supposition that it is.
Many people actually took the Da Vinci Code seriously. I've encountered many of them, so it wouldn't surprise me if people took this seriously as well. It is good to see that even decent secular scholarship will destroy many of these hoaxes without even referencing faith. Now if anyone asks me about "Jesus' tomb" I can simply point out that it has been proven that the whole thesis is groundless.
