IF BZ knew about Nagato having the Rinnegan he could have taken it from him controlled some random shinobi and brought Madara back to life. This didn't happen for some reasons. One of these reasons is that Nagato wasn't known to be Rinnegan bearer. It's only till later that we see BZ finding the Kid and Obito manipulating him. Also I don't think anyone knew about the eyes until Nagato protects yahiko from a ninja. It was mostly covered with hair. considering the fact that Nagato was a shy kid I am not surprised that Orochimaru didn't knew about rinnegan in first meet.

But any "random shinobi" couldn't control the power of the Rinnegan. Even Obito could control only one. Madara specifically choose Nagato for this purpose since being an uzumaki he had large chakra reserves and skills to control the Rinnegan. Also, from my observation, BZ can't possibly control anybody he likes. The person has to either be weak or be in a weakened state.
