I agree about Young Avengers. If DC can have two Titans books, Marvel should be able to do two teen teams as well, there's enough non-X teens that they could have three or four squads (DC have enough for a couple more teams too, hence the constant requests I see for a Young Justice title). The YA would be to the Titans what the Champions are to the Teen Titans (though Amadeus is actually part of both generations - he was previously on the same team as Stature and Jonas Vision, though it was Mighty Avengers rather than YA).
