Kayle AA animation

We all know about Kayle's rather... awful animation for her regular skins. Kayle has some very amazing skins like the new Pentakill or Officer that hardly see use over her Aether Wing skin due to the attack animation on the Aether Wing skin. It's very smooth and feels great to use, her other skins feel very lame due to this. Would it be a good idea for Riot to take the Aether Wing attack animation and put it on her other skins in order to maybe increase play rate (remember Twitch's visual update skyrocketed his play rate, and while this isn't a visual update it certainly goes a long way), or would you keep it the same as it is now?
