The only thing known about the hollowfication incident is that Aizen was behind it, even the cause is referred to as an "Unknown Infection". During the white incident, which occurred eighty-some years after the Hollowfication of the Visored, Kaname states that White is "nothing like the Hollow we've managed to create thus far." He then continues to say that "it's the first one(Hollow) we've successfully created, using the soul of a Shinigami as a base."

Besides, what would be the point of infecting Shinigami like Shinji, and the other Visored, with additional Shinigami Souls? The whole point of Hollowfication was to break down the barrier between Shinigami, and Hollows.
