All you need is another freak seed, then you can name them Ennie, Meanie, Minie and Fred, cause we dont want no Moe!!! LOL That last picture definately looks like it is trying to eat the other one.
The only freaks I've got this year is a few 3 cots, and a yellow cardi that refused to die. I tried to thin it out, so I cut the stem just above the soil line. It is now growing its true leaves about a week and a half later. I seperated it from the one I planned to keep in the first place and figured if it wants to live that bad, I might as well see how far it can go.

Not likely, pod shape is greatly effected by the enviroment... Something that is almost impossible to "clone" with near 100% for each twin. Even the slightest difference will have a snowball or avalanche effect and as a result you will get similar, but not identical pods.
