Sivir proposed buff

I kinda enjoy playing Sivir, but she dosen't feel powerful since her Spell Shield nerf, and a few other abilties/items Nocturne W etc. Before, every spell that you would cast in the 1.5 seconds for Sivir, it would be completely nullified. Here are some example of buffs i'd like to see made to Sivir.

1. "All the subsequent abilities that affect Spell Shield will lower it's cooldown by 0.5 or 1 second"
   

2. Additional spells blocked during the 1.5 seconds deal 50% damage and their CC effects are still nullified.
   

3. Allow her Ricochet Bouncing blade to proc on-hit effects for half the listed value. 
   

Example: I Have and Nami uses her max rank E on me. All my subsequent bounce attacks will deal 42.5 Magic damage +4% of the target's current health alongside other any on-hit effects.

I'm not saying all the proposed buffs to be added in-game. I'm just hoping for one of them to be used at least. Something i want to ask all Sivir players, do you think she needs this buffs, or you think she's just fine without any?
