Lab created chimaera's are not uncommon. There is no splicing of DNA involved, so there is no danger of unleashing genetic mutant monsters upon the world. Some endangered birds are actually being saved by chimaera's. A scientist took some DNA from an endangered grouse, and made a bunch of embryo clones. Then when they hit the notochord stage he spliced the chunk of notochord corresponding with the gonads into chicken embryos with the notochords at the same point in development. The result is a bunch of chickens that are tame, not easily stressed, disease resistant, and lay 300+ eggs a year instead of 5 or 6. The potential to hatch out a large number of endangered birds in a short time exists with a program like that, and the offspring are 100% grouse, with not one bit of chicken in them.
You *could* do something similar with rare snakes.
Splicing cloned embryo notochord chunks corresponding to the gonads into corn snake embryos, and get corns that eat well, adjust to captivity well, but all their babies would be something rare like rhinocerous rat snakes.
On topic, that bicephalic corn is flippin' sweet! I'm jealous.
