Hypothetically, should Irelia ever have her ult healing based on enemies hit, not damage dealt?

Say that Irelia gets nerfed within a few patches and suddenly is underpowered. In that event, one way Riot could buff her back to viability could be to change how the healing on Transcendent Blades works. Namely, they could change it to heal a flat amount per enemy hit (greater amount when you hit Champions), as that would be far more consistent than what's on live. On live, Irelia's Transcendent Blades heal based on the damage they deal, but get their damage hugely reduced by enemy armor, and Irelia players rarely ever get ArPen (i.e. NEVER).

#"But this would make her ult OP!"

You are assuming that Riot would not adjust its stats accordingly. The healing potency could be lower, the damage could be lower, etc. These things would be a tradeoff to making the healing actually consistent and not dependent on how much armor the enemy has (which Irelia can't control).

#"She doesn't need buffs!"

The word "hypothetical" must mean nothing to you. This is JUST IN THEORY.
