First, as should be obvious from the late date of the conciliar declaration of the infallibility of Popes (under certain circumstances) that the understanding of the Papacy has been unfolding. We don't think that Jesus said what he said, and immediately 8 strong men showed up with a sedan chair and a tiara.
I think neither Peter nor James nor anyone else (but only Jesus) knew what Peter's primacy (stipulating it pro tem) would mean. And we just don't know what people called each other in the early Church. Romans usually had three names to work with. Semites tended to do the patronymic thing. I don't know how common cognomens were, but we have evidence in the Gospels that people were sometimes referred to by more than one name.
It might FIT with a certain argument that James's saying Simeon rather than Cephas is meaningful, but I don't see how it proves anything.
...maybe...

Ya got anything in scripture that says Christianity or the church would evolve over the centuries???
Or when the Apostle John writes that what was written (in the scripture) was written so that we would know that we have eternal life??? You're saying that John meant that what was written by the Catholic church a few centuries down the road???
Or that when the scripture says we are not to add nor take anything away from the written scriptures, that that was just a punchline for a good joke???
I'm seeing that we have been warned, in those same scriptures that we should stay away from any religion that comes up with extra-biblical ideas such as those of your religion...
2Co 2:17 For we are not as many, which corrupt the word of God: but as of sincerity, but as of God, in the sight of God speak we in Christ.
