Could Alfred the Great be the "real" King Arthur?

Alfred the Great is, I believe, the only English King seriously considered for canonization. Many Catholics do consider him to be a Saint. His successful defense of Christianity in the Kingdom is highly consistent with the legendary Arthur's devout Christianity and the stories of the Holy Grail. Alfred modeled his Kingdom largely on Charlemagne, whose influence on the whole of medieval thinking is unquestionable. An English Charlemagne would inevitably attract the attention of medieval poets, and inspire a kind of legendary status, along the lines of Arthur. Alfred was a great scholar, whose learning may have even exceeded his military prowess, or, quite possibly, have been the source of it. Again, the medieval poets could hardly fail to find a scholar/king, a kind of English Solomon, unappealing in a unique way. But, poets are not historians. They write of legends, not of reality. Isn't it rather plausible that they created the legend of Arthur on the basis of an essential historical reality that only really conforms to the persona of Alfred the Great?
