Best options to contain Bendis

1) Earth One graphic novel, Flash is short a writer there, cant harm anything in the main universe

2) Batman Beyond. The writing in beyond isnt bad, but its not amazing either. Itd be a good playground for Bendis since the futures been rapidly changing anyways and he can have all the OCs he wants for his supporting casts.

3) This is a suspicion and its not a bad idea since it keeps him away from the established heroes, but there are 2 unannounced Dark Matter titles and with them being near pastiches of Marvel characters, then why not stick a former Marvel writer on one if you got em?
