Regardless that some fans are tired of crossovers, they always sell quite well (some better then others though).
But most of the times the 'stars' of Marvel play important roles. Captain America, Wolverine, Hulk, Iron-Man and Spider-Man have always leading roles. The the X-Men and Avengers are the main teams, sometimes FF included.
But what if marvel would write a Young Heroes crossover, with the FF, X-Men and Avengers only get a small role to play.
What if the kids/teenagers would be the focus of a big massive crossover.
Young Avengers (Kid Lioki, Kate Bishop, Hulklin, Wiccan etc)
New X-Men (Hellion, Dust, Indra, Surge, Mercury etc)
Avengers Academy (Reptil, X-23, Hazmat, White Tiger etc)
Runaways (Bruiser, Nice, Chase Stein, Victor etc)
FF-kids (Franklin, Valencia, Leech, Artie etc)
Braddock Academy (Anachronism , Apex, Kid Briton, Nara etc)
Initiative kids (Cloud-Nine, Trauma, Komodo, Batwing etc)
Do you think it would stand a change??
