Is there a way to revert Lux's voice to previous one?

Hello

Before you start hating on me, I love that Riot is actually looking into old champs that need updates mechanically, visually and in audio. Now for the first one I can always assimilate, for visuals as far as I have noticed they never did a shittier job than the previous model was but the third (for me) is the "meat" of the character once you first hear them. Talking about Lux, most lines are completely removed and replaced with different ones that make no sense to the previous ones, her voice has changed much more and for some reason she now has a character of a complete 14 year old snob girl that tries to hard to be funny or something... Whether you agree or not, it matters not. I just want to know if there is ANY way to revert to her older audio pack before her update?

Thank you for your time, and I hope some of you will know if this is possible!
