But if you look at both this Arc and the Visors as shown in this Arc that Quincies can force a merger with Soul reaper power and the visors are a forced merger between a Soul reaper and Hollow so this means that the merger of both of them can happen when they have a Base of Soul reaper that is how Ichigo though he also has his human base to strengthen that base form when they have a merger so it doesn't self-destruct.
