Season Four and Five Spoilers Everyone.
So I was playing around with the episode lists to figure out how Season Four and Five would have been if JMS had known for sure he was getting renewed for the last year.
In a quote he said the first thing he did was throw out the 6 standalones at the top each season so I put those back in where possible. He's said "Into the Fire" would have been a two parter. He said "In the Beginning" was originally part of "Atonement" and not a seperate movie. There's "In Valen's Name", a comic book which was supposed to be an episode, where the crew discovers the ancient ruins of Babylon 4 being raided by aliens, and we get some Valen and Zathras during the First Shadow War flashbacks. And also the Minbari Civil War was also supposed to actually, yknow, have a war in it.
I cut out "Deconstruction" since it was only invented when "Sleeping in Light" shifted to the new Season Five.
I think we can all agree that the endings of the Shadow War and Earth War were a little rushed, and that the Byron episodes took a little long.
I only have THREE Byron episodes here!!! 
I basically tried to copy the Season Three model of the biggest event taking place at the midpoint (Severed Dreams - Into the Fire - Endgame). The only liberty I took was JMS once said he would have made "Intersections" the Season Four Finale but that didn't really fit into my model.
