I was wondering what they would look like if you crossed them with some of the non BD species. You see a lot of brown x BD and stuff around but I bet none of those started with parents of this quality. Cross these with your albino or some snow leopards and I wonder if what comes out. I want you to keep producing these p14 though, you need to produce enough pups that you'll consider selling some haha.
I agree with you and wonder about the potential appearance of hybrid. There is a breeder in Canada that has done some crosses between Royal p14 and snow leopards. Also Royal x snow x boesmani. I haven't seen them grown out but it sounds like they are stellar.
Here is the writeup from the stingray book I was referring to. My scanner is acting up so had to take a picture. Not that much is in English:
