I see no problem with it. Many people use the snakeskins, and if they snake died, why not use it? Maybe a stuffed and therefor harmless and nonthreatening version of a snake will make someone appreciate the live ones for their beauty?
I've seen people skeletonize a dead snake to mount the bones for display and I find that gorgeous. I was going to send my adult red tegu's body to do that, but the guy in question lost his beetle colony.
I don't want an taxidermy critters in my house, but they don't bug me, and don't offend me. Heck, I once groomed a taxidermied poodle. And now THAT was weird. Talk about pressure! I couldn't say "Well, the hair will grow back over that mistake..."
