Can Bear Cavalry Sejuani Have her Grenades Back Please?

Even as a hardcore D&D fan and memer, the idea of riding a bear into battle was not enough to convince me to spend 1350 on a skin alone. No, the reason I got Bear Cavalry Sej was for the grenade explosion on her E. It was really cool and a big divergence from the normal fantasy aesthetics of the League world, which I think is the whole reason we have skins in the first place.

I'm not asking for a refund, but is it at all possible to have the grenade visual or sound effect added onto BC Sej's new E again?
