I would love to have a Zod be Hot Toys, but I just don't see it happening. If you have the means I would suggest getting the Mattel General Zod and customize him. His body needs to be switched for sure, and the boots/feet fit pretty well into an HT True-Type ankle sockets. The head needs a MAJOR repaint, but the likeness is there.
Here's mine, repainted by a good friend, still on the Mattel body.
