And no, Kael is dead and, as much as I like him (my main has always been BE mage as a homage) he should stay dead. If you want to give BEs a more permanent leadership, develop the already existing characters: Aethas, Rommath, Liadrin, etc. so you can reinstate the Convocation, which was Silvermoon's traditional ruling body.
