I'd like to see him write more about Rhea of the Coos. If I was lucky enough to be included in the close tet that exists on this board if and when the SKMB movie is made, I'd like to be portrayed by that guy who was in that show that I liked. I really liked his shoes. Plus I'd need my own trailer and assistant so I could consult.
Steve was a big Twin Peaks fan back in the day. I always hoped that he would do something with Lynch concerning TP as it is more akin to Steve's writings. But, he opted to do something else with Chris Carter for The X Files and we know how that turned out.....
I thought it would be cool if he revisited the going-back-in-time idea, except within his own universe. He could have new characters (or Roland and Tet) going back in time to prevent events from different novels. Examples:
Tad's death in Cujo, Paul Sheldon's car accident in Misery, Gage getting hit by the Orinco truck.
In other cases it'd be interesting to see how these changes affected the story and thus giving us an alternate novel, essentially. There are several ways he could take this idea. What changes or differences could you foresee? Do you like this idea?
