Hi Tony, it would not be a problem. In fact, it would be very easy to do, but boring.
When I read what folks think about genetics here, I wonder, what they are thinking. Most if not all here think only on the surface. They also use terms like Phenotype. But I am not sure they understand what that means.
Genes are not only a tool that allows an animal to stay current(in exsistance) but they are also a record of its history. Hence, gene sequencing to determine relationships with other species.
Which leads to this. In order to surface old(past) traits, you must inbreed and keep inbreeding. Out breeding keeps current characteristics on the surface, by allowing dominate genes to constantly prevail.
Inbreeding digs deeper into recessive traits which is the past history of an animal.
Once many years ago, I had this discussion with a very talented young herper, Steve Osbrone. At the time, I was practicing lots of outcrossing with montane kings. He was against that at the time(that changed didn't it) During our discussion, I mentioned that outcrossing is not what makes oddities. I mentioned, that inbreeding is how you obtain the crazy stuff, at the time, striped blairs, patternless alternas, non-typical of any normal population.
A couple years when by and he called me up to tell me ask/tell me something. He said, he was breeding his animals pure, but a strange thing happened. His pure greeri, produced a perfect thayeri. There were also a couple other examples of that.
In reality, I do not think(or needed) large numbers to accomplish that type of result, you only needed multiple generations of direct inbreeding and the selection of traits you are looking to surface.
Again, this is only theory in how it works, but not theory in that it works, as we did do this very thing many many many times.
The suspect that continued inbreeding reveals a common ancestor amoung closely related species or subspecies.
In my experience, inbreeding never expressed the current F-1 color and pattern. After three generations(average) of direct inbreeding, the offspring were very very different then the adults. After 8 to 10 generations, there was no indication of a locality specific pattern or color. Cheers
