Experiencing an animal birth is a beautiful thing. For me it was when I had just moved out on my own and decided to let my cat get pregnant. It certainly wasn't a responsible move, but I did end up finding homes for the kittens and the story had a happy ending.
It sounds like you've given this some thought and are going about it the right way. It is true that most people will be of the opinion that breeding should be done only between purebreds, and to better the breed standard, so you may get a few responses like that. But if you are sure to find them pet homes and you know that your bunnies don't have any problematic genetic disorders such as malocclusion, the experience can be rewarding.
The only advice I can give is to be wary of the complications that can arise. Be prepared for some of the kits not making it, or your doe having difficulty with the birthing process. Many heartbreaking things can come from breeding, and you should know about them before you proceed. Good luck!
