Honestly, I have an idea for a new round, but I'd rather someone else do it...
Dreamcasting # X - Batman Begins Franchise Sequels
Basically, recognizing the tones set by Batman Begins cast these characters in such a way that matches those tones... Maybe even explain (particularly for some of the more implausible villains), how they come to exist in the world of BB and TDK.
I think I'd put the characters to cast as: Harvey Bullock, Renee Montoya, Crispus Allen, Selina Kyle, Mr. Freeze, The Penguin, The Riddler, Poison Ivy, Talia... With Optional Dr. Harleen Quinzel, The Mad Hatter, and Clayface...
I'm just throwing it out there for anyone who can't think of something, but if I win, I'll put it out there, and do a cast for it anyways, because I have three of them down pat, and some ideas for the others.
