Howard,
No, certainly not intentionally at least. Three weeks ago, while fishing with my grandson, we caught what looked distinctly like a CNBG from the TGG pond. I have no idea how that fish got in the TGG pond. It was about 6 inches and fat and had the beginnings of the copper bar across the nose. Nature finds a way.
Regarding consequences, the strategy in this pond stocking was to grow out the target fish, the original stockers, to whatever size they could attain. GG's are reportedly about 70% male, unlike regular HBG which are reportedly about 90% male. Adding GG's to a pond with CNBG or adding CNBG with the initial stocking would simply introduce more of the "undesirable" Fx offspring....more females to breed and cross breed. I say undesirable because in this case the target fish are the original stockers and all other fish detract from the growth of those target fish. Most people that sell HBG and/or GG's all recommend that they not be stocked with other BG for that reason.
I haven't seen it in writing anywhere, but presumably the offspring of the GG and HBG have a more normal distribution of sex, i.e. more females and closer to 50/50 ratio. Regardless, the population of fish in the pond is certainly best controlled by minimizing the number of surviving offspring and not adding to the female breeding pool.
