Galio Rework Idea

Galio is such a cool champion and i would love to see him become even more cool.

So what i'm think is changing his passive and his e and then giving him a visual makeover in both model and abilities. For Galio's passive I would push it towards a tank passive, being that Galio was made with the purpose of being a magical damage tank. Personally, i would do something like:

"made of stone": Galio is too heavy to be knocked up.

Or "Persistent effects are 30% less effective"

Or "consecutive strikes against Galio deal 5/10/15% less damage"

For Galio's "e" I would like him to have like a Caitlyn "e" mixed with his existing "e". When shooting his wind trail he now instead of doing some dmg he knocks enemies back like alistars knockback. If enemies hit an obstacle they are stunned. When Galio use the ability he dashes backwards. Same range as Caitlyn. "e" still leaves a movement speed trail for maybe 15-10% speed bonus. What do you guys think?
