I'm doubtful about Blockade Billy as well, since it did get a standalone release and not just as an e-book or a limited edition.
My guesses-
Stories-
UR
Premium Harmony
Herman Wouk is Still Alive
Mile 81
The Little Green God of Agony
The Dune
Batman and Robin Have an Altercation
Afterlife
The Rock and Roll Dead Zone
Summer Thunder
Bad Little Kid
That Bus is Another World
The Glass Floor (because it was reprinted in 2012 by Cemetery Dance and in 1990 by Weird Tales, so obviously he doesn't mind this early story being available)
Poems-
The Bone Church
Tommy
Mostly Old Men
The Dark Man (because it was recently given a special edition release via Cemetery Dance)
Essays-
The Ring
Guns
Wild card selections (unlikely, but not impossible)-
Weeds
The Crate
The Blue Air Compressor
The Night of the Tiger
Man with a Belly
Leaf-Peepers (1998 New Yorker essay)
Cone Head (2002 New Yorker essay)
Heads Will Roll (Under the Dome script)
