Well since we're talking about artificial DF here, there could be some important person with the real lion DF somewhere in the world and the two would co-exist normaly.Also since we don't know a lot about artificial DF there could be a chance of multiple fruits of the same model existing at the same time.If this is true Kaido could have like 5 lion DF so he wouldn't mind wasting one on a minor character.

I still agree it's pretty unlikely by the way..
