Don't go by that art.
According to the plans, each Dumbo will be the same size and have 16 flying elephants. Only difference is one goes clockwise, the other counter.
I have no idea if they are re-using the existing Dumbo, though I suspect they would want to.
Agreed. They probably still have the molds from the new elephants, and have drawers full of the spare parts. Why re-invent it when you can reproduce it?
Take most of it apart, get a big crane, lift it, and set it down in the new location once the other one is done. Minimal downtime.
