If you want to do an alternate WOT5K, maybe a divergence of killing off Joffrey early would work. One thing I've noticed consistently is that very few players ever want to do anything that helps Joffrey on the IT. Probably because we all know much more about him than would the IRL lords of Westeros. I think the best and only "successful" Joffrey game involved him nuking King's Landing on turn 2 or 3. A WOT5K scenario with King Tommen from the start might change the dynamics somewhat.
It would be interesting, could he be pushed from the walls of Reed Keep by Sansa perhaps ? , of course Cersei would execute Sansa because of that but maybe it would make everything more interesting, with that said I wouldn't mind if it is done a game that follows the canon until the beginning of the War of the 5 Kings, I would play in any of the options.
