First of all...there absolutely IS a market for hybrids in MOST species of snakes...colubrids, pythons and boas.
Secondly, it happens all the time. How many "true" red tail boas are being sold in shops? How many "true" BCI are being sold in shops? How many "true" dwarf boas? Hogg Island boas are on the verge of extinction because of so much intergration going on in the private breeding sector.
Than you look at hybrids like Rootbeers and Creamsicles, and obviously there is a HUGE market for these snakes...you can find them ALL OVER. Jungle Corns, Sina-corns, Corn-durans, King Snake intergrades...you can't escape hybridization, and some of the crosses are absolutely fantastic looking. Someone posted a picture not too long ago of a Ball X Burmese...that was an incredible looking snake.
The bottom line is that we, as human beings, have always experimented with what Mother Nature provides us. There are dog/wolf hybrids, horse/donkey hybrids(for several hundred years), untold numbers of fish species hybridized...and the list goes on. Most of them are viable and valuable life forces. Some of them simply don't work. I don't think there is anything wrong with experimenting. 98% of what we know today as regards different species of animals and husbandry is based on someone having the guts to go against popular opinion and see what would happen. Even higher percentages of what we know as regards captive snake breeding and care has come through experimentation. You can't discredit one brand of species experimentation while at the same time accepting another. And ironically enough, if you keeps snakes as pets, and follow any of the popular literature...you have accepted species experimentation, and adopted it's findings.
Who is to say that 20 years from now, what is being discovered currently through intergrade and hybrid experimentation doesn't break open a whole new world of knowledge in the field of herpetology and herpetoculture?? You never know until you try, and I am firmly of the opinion that it is better to try and fail than to never have tried and leave all those questions unanswered...
