Hmm...
Sometimes, It's possible,
For example, You can have one Arrow autocast and one different class autocast working together just as easy, Why? Check out famous Spellcraft! I don't think there is much difference,
But making Heal and Raise dead, as Murlock has been talking could be serious action! I gotta check it out in my WE, And it can be easily made with latest patch, I guess...
Even it's possible to make through triggering, like making Fairy Fire (Ooops. Mis-spelled), Raise Dead, Inner Fire, and Curse autocast, simple eh?
