Personally, I'd like to see Marvel do a big daikaiju summer crossover event. Doesn't seem like it would be difficult.
The Elevator Pitch.
- A bunch of Marvel's classic Giant Monsters appear at once and begin wreaking havoc on the world, a la Pacific Rim.
- A core team of superheroes tries to uncover and shut down the mastermind behind the attacks. (There's your main story for the event miniseries.)
- The rest of the superheroes fight the monsters. A different monster could spontaneously appear in each ongoing series OR you could package them in a separate miniseries (a la AvX VS), whatever you wanna do.
- Climax: The superheroes trick the monsters into turning on each other. Giant freaking monster battle.
- Spin a Red Ronin series out of it, tickle some of the fanboys for about 12 issues.
- Give it an ominous, one-word name, like "MONSTERS".
