Nah, Zeus and Hera were incapable of doing that, Nami even less so.
Didn't Zeus hit Kid hard during Roof Piece? I love Big Mom, but... uh... Big Mom is crazy and dumb a lot of the time, losing herself in her emotions.
I'd trust Nami to use Zeus much better, as Oda has stated Nami is incredibly smart. She was apparently the 3rd smartest character in the East Blue, and I think she's gained intelligence after studying weather for so long in Weatheria. Nami with Zeus is a horrible match-up for Kid. Big Mom would rely on her strength, while Nami would spam Zeus over and over to stop Kid from gathering/using metal.
