Well. I said the orange ghost because pairing her with anything else will only give you that co dom if paired to a co dom and normals. You would also have no idea if any of the normals are possible het for the hypo. Since its a recessive trait id stay away from anything else recessive or you get nothing but normals unless its a het orange ghost. Theoretically of course. But people have hit the once in a lifetime chance of beating the odds with recessive traits before so you never know for sure. The only other thing id say is a proven visual pied. Then You'd have a project on your hands and probably have to hold back all of them for breed backs but you could make the first orange hypo pied in a few years if you worked with it.
