User blog comment:Wario1226/Junglers as Supports/@comment-5907289-20130809124033

For my part you can play whatever you want as support as long as you keep the ADC safe and don't steal his farm. But I have played with Shaco support and his boxes didn't work out. They just stay out of the bushes and pink the lane. If you want to play an unusual support, please know how to play him like that.

I do have one comment on jungler tanks as support. Leona is a great tank support because she gets a crazy amount of resistances from her W, but most jungler tanks don't. They rely on their items to get tanky and items require money, something sparce with supports.
