Would Sion's Old Ultimate Fit Aatrox?

You know, the one where he gains massive lifesteal (kind of like Aatrox's W when he's below 50% HP), and heals his nearby allies based on how much damage he can deal.

Aatrox's lore brings up an ancient battle between the seemingly victorious Magelords and the "outnumbered, exhausted, and poorly equipped" Protectorate army on the final day of confrontation that would of ended in their inevitable defeat -

"Just when all hope seemed lost, Aatrox appeared among the ranks of the Protectorate. With but a few words, he urged the soldiers to fight to the last before throwing himself into battle. His presence inspired the desperate warriors. At first, they could only watch in awe as this unknown hero cleaved through their enemies, his body and blade moving in unison as if one being. Soon, the warriors found themselves imbued with a potent thirst for battle. They followed Aatrox into the fray, each fighting with the furious strength of ten until they had won a most unlikely victory."

It would fit his theme a lot better than his current burst/steroid ult, especially since Sion is no longer using it. More of an aura, that could potentially scale off of Aatrox's W, e.g. -

Passive - Blood Thirst now heals all nearby allies on it's third hit for 30/40/50% of the amount Blood Price now grants allies 30/40/50% of Aatrox's bonus attack speed from Blood Well Active - Removes all crowd-control effects at the time of cast and fills Blood Well to maximum (much lower cooldown - near GP's orange level, minus the heal)

The way this is done is to avoid Aatrox just being a basic aura tank with stats, and instead scales ally bonuses with how well Aatrox is doing in combat i.e. gated by his other unique kit elements for example having a full Blood Well and lots of 3rd procs of W = maximising ultimate's passive, empty Blood Well after revive and getting kited with ult on cooldown = no bonuses for allies. Throw in a reliable element like a CC removal on active and on-demand Blood Well, remove the huge AS steroid, range bonus, and damage component to offset the passive power gain and making Aatrox himself more item dependant, and we're done.
