Aizen has always seemed IMO to be someone who plans out every step way ahead of time, and as such, is always planned for every outcome. I don't think he was stressing at all about possibly being found out or even his plan working because he's so sure of himself. He has the brains, the power and most importantly, the confidence to attain anything he wants. There's never a moment of doubt.
