The titans would have to make sure they take out Magik and Warlock first. Warlock cannot be touched if he doesn't wanted to be (by initiating the transmode virus/life glow absorbing) he's also from a race of beings that can become big and strong enough to tear a star in half with relative ease, if Magik sees one of her friends die she will embrace her dark side and then the world will once again teeter on the edge of the abyss. Magik is a killer who has her own dimension and an army of demons.

Cannonball is invulnerable when blasting, when he was with the New Mutants that was well a well established fact, until later on in life when the Fury hurt him in his blast field, Mirage is Moonstar and none of the titans have psi to properly defend them from her power which would distract anyone effectively. Cypher can also read body language and Warlock would more than likely protect him by transforming into body armour, he could sit back and predict their opponents moves. Magma can also become untouchable in her magma form.
