First of all, Zed's core spells all let him attack at a distance. There's nothing forcing him into melee.
Second, they're all AoE, so Zed would only receive 1/3 of Spell Vamp's effect per target.
Third, Spell Vamp has been proven to help bruisers more than assassins, and bruisers are already in a good place, so buffing AD casters will have to be done in other ways (like Black Cleaver, hint hint).
If you want Spell Vamp that badly, ask your AP to build WotA. They scale with it perfectly, and you get free stats; who cares if YOU can't use the 30 AP? You didn't pay for it.
