As someone who's had a Druid main since 2000, I would recommend against it.
The thing is, where you CAN kite, it will be awesome. The problem you'll run into... there won't be that many great places to kite.
If you're just looking for a combo that will be used to grind AA's, and you're confident you'll find enough hunting grounds so that you don't log in and find you have nowhere to go, then it will work fine. If you want a combo that will have some good flexibility, and be able to go most anywhere, there are better combos out there.
With a tank and cleric merc, the Mage/Wiz combo would work fine.
Come to think of it, once VoA comes out, you'll be able to have two mercs per char (not at the same time, but can switch between them). So yeah, I guess your idea is fine, will be limited til VoA, but then you'll have lots more options.
