Possible ability concept for Yone, if he becomes a champion

I was always fascinated by martial arts and weaponry, especially since I grew up on martial arts movies and I myself am a martial artist. One particular technique(some people call it a martial art but it's really not, it's just a technique) is iaido. The image of a samurai or ronin cutting through an enemy with a drawing strike is indescribably awesome to me. I want this to be implemented in League in some way, especially since there's a chance that Yone may come back in the future, even with the rumors of him being fake. So here are a few concepts that would fit perfectly.

Concept 1: Ki Concentration/Iai Strike/Quickdraw Yone charges up, slowing yourself slightly for up to 2 seconds, increasing range and/or damage. Recast or at end of channel to A:Slash in an area in front of you B: Slash in area in front of you and dash a large distance, both or one of them’s dmg and/or range increasing with charge time C: Dash a large distance in direction you are facing D: At max range or upon hitting an enemy champ, damage all enemies in a huge zone(think bigger version of camille w) in front of you with several powerful slashes. Each slash deals massive physical damage. At max charge, the slashes pull the enemies back instead of the direction you are facing

Crowd control does not interrupt the charging process. (Maybe: Increases damage if you didn't move during this)

Concept 2: The Wind at My Side Cooldown: 8 seconds Yone's first basic attack periodically deals bonus enemy max hp damage to the target and all enemies in an area around/behind the target. Targets hit by this take extra damage from Yone's abilities and autos for a few seconds.
