Absolutley not. Read the last few verses of Revelatin 22 to see why.
Absolutely yes. Tell me where in the KJV one can find the following books: Tobit, Baruch, Judith, Wisdom, Ecclesiasticus (Sirach), 1 Maccabees, 2 Maccabees, seven chapters of the Book of Esther, 66 verses of the third chapter of Daniel, called the Song of the Three Children, and the thirteenth and fourteenth chapters of Daniel which were discarded by the Reformers? Had Luther gotten his way, even more of Sacred Scripture would have been deleted; as but one example he referred to The Epistle of Saint James as "... an epistle of straw, with no character of the gospel in it."
Apocalypse 22:19 "And if any man shall take away from the words of the book of this prophecy, God shall take away his part out of the book of life, and out of the holy city, and from these things that are written in this book."
