The gospels in our Bibles are there for a reason. They are the only documents that go back to the first century and authenticated by the apostles, which is why they were never in dispute among the early church. The other "gospels" you cite are second century gnostic nonsense, not historical texts. I refer you to Luke Van Der way's (possibly butchering his name) study on onomastic congruence. The gospels achieved 86%, second closest was Josephus on 7% and the lost gospel you cited had zero onomastic congruence.
