Can weapons die? Or can there be an artificial zoan of the same type as an existing zoan?

I'm asking because a lot of hints have been dropped that Jack has a zo zo no mi.

1. Jack's figurehead is an elephant.

2. Along with the "claw marks", (tusk marks?) Jack left a footprint the size of an elephant's.

3. Um, a third thing.

Okay, so maybe not "a lot" of hints, but it would make sense, given that Kaido has an army of zoan users, for one of his top guys to have such a powerful animal.

So I'm thinking either Funkfreed died somehow or Jack has the ancient zoan zo zo no mi model: Mammoth or legendary zoan model: Vishnu or some such. If it weren't for the relative unlikeliness of a sword dying, I would call elephant powers right now. Although there remains the posibility that he has the elephant version of whatever power Sheepshead has, if that turns out to be a paramecia.
