It could be done if we pick the best of the best (because if this is Death Battle; Supes is going to one shot Cap, Hawkeye, ect..). So considering consistent depictions and ignoring prep time... And ignoring Xmen and Fantastic 4 (to simply things)

Justice League

 * Supes
 * Wonder Woman
 * Green Lantern

Avengers

 * Thor
 * Hulk
 * Nova

Dr. Strange and Dr. Fate are basically the same so I see no reason to include them. Same with Shazam, Supergirl, Krypto, Martian Man and Superman; although Superman is arguably the better of the bunch. Flash is basically Superman without the strength and indestructible skin so I'll exclude him as well.

Ghost Rider is more of a lone wolf, I don't see it necessary to include him. Also he's immortal so that's cheating. Squirrel Girl is OP so no.
