I could see room for removing Revelation from the canon, as it is never used liturgically. However, there's also nothing in the book that contradicts any part of Tradition, so there wouldn't be any pressing reason to remove it. NT deuterocanonicals such as the Shepherd of Hermas have fallen out of use centuries ago, and I don't think anyone would seriously argue for their inclusion now (although a publisher may decide to include them as an appendix).
The real battle for the canon today is in the OT deuterocanon (Maccabees [up to 4 books depending on whom you ask], Tobit, Judith, 3 Ezra [Nehemiah is 2 Ezra], Wisdom, Sirach, Baruch, and a couple of chapters of Esther and Daniel). Some of these books have questions as to their usefulness, but others have been clearly established as liturgical. For example, the Song of the Hebrew Children, which is usually excluded from Daniel, was sung as a prokeimenon (a short verse preceding the Epistle reading) yesterday. This passage I would argue very strongly to include. Others are not so clear.
Otherwise, we do have the same canon as the rest of Christianity, especially regarding the NT.
