Howabout an alternate version of Stephen King characters coming together and fighting evil?
Could feature :
Carrie White
Older version of Firestarter
Dimension hopping Roland
Lead by John Smith from The Dead Zone. He can see the future and is trying to stop "R.F" (whatever name Randall Flagg is currently using)and his big scheme...
Others?
Are there other characters from a writer you like that should form a team?
