I'll bet you probably can, for a really big pile of money. But you would be disappointed because it's likely not reproducible in any consistent way. I've seen this happen with several other people. It's never happen for me though, but I really wish it would so I could document it. It's still a mystery.
That is a strange change. I would have thought genetic, but that's almost impossible just from a breed and shed. Hormonal changes are all but guaranteed from a breed which can effect coloration, but this is a really extreme color loss, not just shift. Pigmentation changing density from hormones makes perfect sense, but loss of coloration to straight gray just doesn't quite click, but I'm no expert.
