Will These Beasts be a New Breed?

Ghidorah has had several incarnations over the years. There was King, Grand, Cretaceous, Death, and Kaiser Ghidorah. So has Mothra. There was a Rainbow, Leo and Aqua Mothra. Would it be a good idea to make a new breed of Ghidorah and Mothra for the sequel? Will there be multiple Mothras, each different renditions of previous types? If so, which previous incarnation do you think these savage brutes will be closest to appearance-wise?
