Hopefully you aren't relying on Romans and Pauls reference to Hosea.
Are you aware that there are books that were left out of the Bible, not for reasons of authenticity? Paul features prominately in one of those books. Are yo aware he built churches in Europe? 
He did a great ministry in Rome. Read the New Testament. Plus, there was his ministry in Greece and in what is now Turkey. If you're going to start dragging in other writings, we all can. "Harry Potter Meets Paul", would be a start.
Either you go with the established canon, or you bring in whatever you want. Joseph Smith had a very good time with that, and so have others.
