There are a few things I'd be cool with, though not all would work.
1. A "Metropolis" Comic following the comic versions of Smallville characters for a few years.
2. A "Metropolis" TV show focused on Lois, law and order, the Planet, with Supes more assumed and in the background. That would be a tough one, but it would have to be a VERY character-driven show.
3. A GA/JL spin-off.
4. A new Superman animated series starting where season 10 ends.
