What you have is usually called a sport rather than a reversion, since the parent wasn't a green hosta.
I did see that Paradigm was a sport of Abiqua Recluse (registered in 1999).
Another sport of Abiqua Recluse (discovered by sombody else in 1999, but not registered) looks like the green hosta we have. Can't really say that it is Glitter though, since they sported from different hostas at different times.
