For the animals perhaps no problem (although some subspecies may have different poisons...), but for the future these actions are problematic, as they will surely interbreed and who wants those hybrids? I certainly not. I don't even mix animals from the same subspecies from different localities, but that's all up to the one who's keeping the animals. You have to find out your own philosophy. But I would like to encourage to keep animals from different origins separate, even if they belong to the same species or subspecies.
