So we arent talking about the historicity of the gospels but the history of a specific translation That is not how historians treat ancient sources The Gospels are works from the first century written in Koine Greek  not the modern translation you may have on your desk I left the List of Bible verses not included in modern translations which you added to appease your desire to go off topic talking about translations the Johannine Comma which isnt in the gospels and other things which have little to do with the historicity of the gospels Similarly textual criticism isnt that big a deal regarding the historicity  of the gospels or theology The two big ones which could weigh on the question of historicity are dealt with even though most scholars wouldnt include them in an evaluation of the historicity of the gospels as they arent really gospel material
