Could be worse, he could be Barry Dylan.
As for whether or not he could return... honestly, I wouldn't put it past the show. I mean, yeah, he had kind of a Disney death, but he's not dead dead, just... kinda turned to stone and shattered. With a bit of care, glue and ass-pull magic, he may as well come back. Hell, they gave Discord a second chance, and he tried to break reality itself.
