Sure, that could work, but Tolkien was not super specific about the nature of his vampires. There were some that were specifically vampires, and some were other creatures taking their form. It would seem that, given the description of Suaron "dripping blood from his throat over the trees" that Middle Earth vampires were at least similar to classical vampires, but we do not know for sure.
