Sated Devourer Jax + Galio's Bulwark.

Has anyone tried this yet? Go a full AD build except Botrk and devourer and potentially berserkers greaves (id go merc treads), or some MR. With his ultimate, assuming he has ~300 AD he will have well over 200 armor and 150 or so MR. Throw Galio's bulwark on him and you've got an unkillable tank that does more damage than an adc for 4 seconds. With Bloodthirster you lifesteal more than you lose.

With devourer + bork + passive you can achieve nearly full AS. Your ultimate passive triggers it's bonus magic damage every 2nd hit, your empowered procs twice, and I'm not sure if it stacks his passive faster.

EDIT: Forgot to add the on hit damage is magic, so you do a massive amount of mixed damage as well as true damage from red buff/bork. Basically it's impossible to itemize against, your lifesteal keeps you at nearly full health, you have an aoe stun and 2 second pseudo blind, and you deal more damage than your adc.
