I don't see anything on a linguistic level concerning the names of the apostles to support the idea that the gospels are a myth.
Have a look at Dr Richard Carrier's lectures on youtube, there are several and they are very interesting.

He talks about how the language used in the gospels directly suggests that the writer of the gospels was writing allegory not history. He originally was trying to prove the historicity of jesus but found overwhelming evidence that he was wrong in his assumptions.
