I doubt it. Kender are temperamentally unsuited to be Wizards of High Sorcery - there is a reason not a single one ever took the test, much less passed it. Of course, there is no reason an older Kender, especially one who has seen enough in his life to take a more serious outlook (do they exist? They must, someone /IS/ raising little kender, after all) might not be capable of finding the energy and devotion. It just hasn't happened in the history of the Towers.
