Maybe if you took Illusion's silent casting perk, this idea could work. Still though, magic does not receive any bonus from stealth, so the only way stealth is going to help you here is from a defense standpoint (i.e. not being killed because enemies can't find you).
EDIT: by the way, my current character is a mage with a bit of stealth. Though, he isn't focusing just on destruction; he's using all the schools, but with a focus on conjuration, alteration and destruction.
