User blog comment:Wario1226/Junglers as Supports/@comment-3974211-20130810170604

I've actually seen Shaco support played as a Blitzcrank counter, due to his ability to create grab-barriers. And Jarvan support was a thing in season 2 which only really stopped due to a lot of itemization changes - although it can still work. Nautilus actively sees support play, as an alternative to Blitzcrank and Thresh. Maokai is far too mana hungry, from my experience (and I have tried it).

The rest of them don't really have the build-incentives or the range-type to function as a "support". A kill-lane maybe, but as with all kill-lanes - if you don't get kills, you can't afford both the champions.
