Jax -- a possible support?

The off meta support train continues it's trek around runeterra.

Hey there, Master Fledgling here.

I've always liked Jax. Never been terribly good with him, but he's really cool. He's like a mix between Tony Stark, Batman, Captain America and Spiderman -- a normal human (Maybe? We don't even know. Mysterious +2 points) with an apparent chip on his shoulder, but not so tormented by his past that he can't fool around and function in normal society. Just generally awesome.

And regardless of my skill with him, I have long wondered if he could function as a support. A hard engage via his jump, a nice, AOE stun, can just about ignore the enemy ADC if you play him correctly, has damage with just a single item and then can go tank, etc, etc. He'd not be perfect and, my guess already? He needs lots and lots of farm to be a hyper carry.

But what about just a tanky, quasi-damage support? Not quite as tanky as Leona, but a simlar idea. Not quite as useful as an Alistar, but close. Not the terrifying 'support' that is Ziggs, damage Gangplank or Fiddlesticks, but certainly capable of brawling and can build damage if he is so blessed to be in a position for it.

He's really well rounded and can be built effectively tailored to the match he is in, such are his AD and AP scalings and his natural ability to press a one of two buttons and thumb his nose at enemy damage for a notable time period.

I dunno. It just sounds swell on paper. Let me know if this has any sort of merit. I'd love to pick up my lantern again and go to work in a slightly different lane than usual.

Thanks as always,
