Sivir's Boomerang Blade

I feel like it would feel cooler if it worked more like an the bouncing Chakram Xena has.

Nox already had this type of weapon in their game, and League didn't really have walls interacting with abilities during Sivir's remake.

I know she'd lose the potential to snipe over walls with this, but I feel like the potential to bounce multiple times would give it the potential for extended range, more interactions (bounces/distance to damage etc) and also give her places to shine with it (those places being pretty enclosed).
