One Avengers title, not exploiting the current cash cow?
Now, I agree with your plan with some tweaking.
-Couldn't agree more with the Malibu/Ultraverse characters. Shit or get off the pot, Marvel. i miss Strike, Shuriken, Lord Pumpkin, Rune, The Night Man, etc, etc...
-Replace 'Master of Kung-Fu' with Heroes for Hire (Luke Cage, Shang-Chi, Misty Knight, Night Man and others...ethnically diverse, street-level team)
-Go with the current all-female Defenders, replace 'Deathlok' with 'She-Hulk', and and 'Marvel Man' with current 'Captain Marvel', and you have more female titles.
-There are more than enough mutants characters to support more than three book. All-New X-Men, Uncanny Brotherhood, Wolverine & The X-Men (the school), X-Force, and X-Factor, plus solos for Wolvie (cash cow), Gambit and Deadpool, and a Sabertooth & Mystique team-up book.
-Avengers can support two titles-East Coast and West Coast, ensuring different line-ups.
-Guardians of the Cosmos (Galaxy seems far too pedestrian)
-New Warriors (Young Avengers, whatever)
But then, right now, as long as I keep getting my high-quality Gambit, Hawkeye, and Venom series monthly, along with upcoming Cable & The X-Men, you can do whatever you want with the rest of the line...
