@Protection- Hold off Aizen until Ichigo returns? If I'm not wrong, time stops in the Dangai World so there would't be any lag in which to hold Aizen off. Besides, if the former Captains couldn't do it, how could Kiego, Karin and Co.?

I'm not going completely against what you said, just proving a point.
