With Marvel having their movies and TV shows all connected what if DC went another route. Right now we have Arrow and The Flash on TV with Legends of Tomorrow on the way. Then we have Batman V Superman to kick off the DC cinematic universe. What if they crossed the two over in a multiverse. It would give writers the freedom to tell whatever stories they wish but still allow for big team ups and characters meeting. DC could build the Cinematic universe up in to crisis on infinite earths which could feature anyone.
