Thought we could use a break from the normal discourse, and I came up with a fun activity: turn what we know of the original outline into an actual story, akin to Wikipedia plot summaries. For example, here's how I think it would've gone:
Book 1: Would've spanned from AGOT prologue to just after the Red Wedding. Tyrion would've marched the Lannister armies north and taken Winterfell, while Catelyn, Bran and Arya have been captured by Mance Rayder beyond the wall. Jaime poisons his entire family, including Sansa and her child with Joffrey, and frames Tyrion (who would've actually killed Joffrey) and takes the throne by virtue of being the winner.
Book 2: Tyrion rallies the North to him. Before Jaime marches against him, Dany invades and deals with Westerosi politics. Catelyn is killed by the Others and ressurected (I believe Stoneheart was a reworking of the original Catelyn killed by the Others plotline) and she is mercy killed by Arya while Bran learns about his powers. The Starks return to the North (Mance would die somewhere somewhen) and Bran is seated in Winterfell by Tyrion, and Bran hates Jon for not aiding the Starks. Jaime is killed by Dany, who takes the Iron Throne as the Others break through the Wall.
Book 3: Given we have no idea of how the story ends, this is probably the most bare. I only have that Tyrion exploits Bran's hatred for Jon (referenced in the outline) to try to woo Arya in the infamous love triangle.
What are your ideas on how the story could've turned out.
