Tribute to Late or Lost Pets

My minecraft horse is gone, because of a glitch. Don't worry Mojang, (or microsoft, or Xbox Live support, or whoever is the one reading this), its got nothing to do with the minecraft software itself, the problem is no doubt with my device, and my habit of constantly restarting the game to rollback to the last autosave. After doing this for the umpeenth time (because my horse drowned yet again - this happens very often), i found he was gone. just gone. as if he disapeared in thin air - as if he had never existed at all. All that was left was a dropped lead on the ground. I restarted the game again, but of course it didnt do anything - i was already at the point where it last autosaved. I am already starting a giant project to find an Ink Sac to make a book and quil with a special message, which i plan to place alongside lots of flowers at the location where he was glitched out of existance, but it got me thinking. It would be so good (i mean, such a good idea - of course its too sad to be good, but you know what i mean) if there was a feature where players could craft and leave a tribute for pets that have died or have been lost (and cannot be found), or glitched out like my horse, or anything like that. Preferably a recipe which's ingredients are easy to obtain, if not completely free to craft. Like a cross or tombstone, or even just granting the player several flowers of every single type/variety for free without having to actually go out and find them.
