You were asking if cybisters and H papillae could be crossed. According to Read's "Hippeastrum" book, cybisters are a fairly recent group of hybrids (only available after 2002), from the American breeder Fred Meyers. He died in 1999 but his family has continued the breeding operation. As a group, the cybisters are exotic, with unique colors, shapes and even growth habits out of very small bulbs. I have no idea if you would get fertile seeds out of the cross of a particular cybister hybrid and H. papillio.
