It is not possible to create a viable population of any animal by starting with a breeding pair and then expanding the population by encouraging incest. Even ignoring the problem of birth defects, when a population's gene pool shrinks beyond a certain point and genetic diversity in the species is eliminated, the species becomes extremely susceptible to new diseases. Without genetic diversity in a population, a deadly disease is much more likely to kill 100% of that population.
For example, cheetahs are consider a threatened species because of a population bottleneck about 10,000 years ago. This bottleneck is nowhere near as extreme as the one Creationists propose for humans just 6,000 years ago, and yet cheetahs are so closely related to one another that transplanted skin grafts do not provoke immune responses.
