Yeah there's one problem: the Hogyoku doesn't make Shinigami Visored unless someone in the area wants them to. There was no one in the area who wanted that. And a sudden dramatic increase in power isn't abnormal, you see it plenty of times where a Shinigami on the ropes suddenly gains an increase in strength. And Ichigo was in control of his abilities, rather than lose control.
