Hello, well i think they could make such a figure right now, except for the "improved" snake body and the (bloody ridicolous) sandals they have all the components they need. The head should be just a repainted version of the current one, with yellow helmet and no mask. That's unless you want the "caricatural" head, in this case you'd need a resculpt. You sum up the oter pieces yourself (well done), and the weapons are already there.
Cheap and easy, i say.
