hybrid question

Not being a fan of hybrids I'm lax in what has been done. I'm curious whether the Leucistic form of Elaphe obsoleta lindheimeri has ever been crossed into the gutata (especially the amels)? Have you ever seen/heard of it? what did the F1 & F2's look like? The thought just sorta crossed my mind while looking at another thread and if I got an adult male I could have F1's next season but would be less interested if it's been done. Thanks for any info.
