Batfamily vs Superfamily (DC x Marvel)

When the world needs to see the Justice League and the Avengers become one in order to stop the Earth's reoccuring problems and threats things don't start off so well.

Batman, Bruce Wayne and Iron-man, Tony Stark are cousins but what Tony doesn't know and what Bruce tries to keep from him is his secret identity.
But can he? And for how long?
With the Batfamily trying to keep Gotham in tact while Bruce and Clark work with the League and now reluctantly the Avengers.
And the Superfamily trying to readjust to their new living arrangements not to mention the company of having to live with the Waynes.

How will things turn out for these two hero abiding families?
