Jax and the Darkin

Ok so just a bit of a brainstorming, "what if" scenario of non canonical lore. Jax . The given of Jax being Saijax of Icathia, it is confirmed he has killed at least one "god warrior" shuriman ascended, even before the void outbreak. He is the MASTER at arms (important for later). Now to the other part of this. The darkin. They are corrupted shuriman ascended. Specifically for this example ill just use aatrox because him being the darkin of war kinda fits with Jax's combat prowess. So the scenario. Jax encounters aatrox (or rather his current host wielding him). Jax has killed ascended before, and him being as experienced and skilled as he is (arguably unbeatable by any mortal in 1 on 1 combat), I'm sure aatrox would be a challenge but I believe jax could defeat him. Jax would then take up aatrox, the blade. Normal mortals would struggle for their lives for the power of the weapon over the darkin (see kayn and rhaast), but jax is THE grandmaster at arms. And he had survived countless fights and the void itself. Both physically and mentally, i believe he could overpower the darkin and harness the full power of the blade. Even in game, aatrox has a voiceline where he calls jax a "worthy vessel". So imagine this nigh unbeatable duelist now possessing the full unbridled power of a darkin weapon (again see shadow assassin keyn)? The void wouldn't stand a chance. Again just a brainstorm I felt like sharing. If there's anything inaccurate here, please go ahead and let me know. (yes I am an absolute jax main fanboy)
