Small Sivir rework idea

I feel like one the the problems with sivir is that she's normally a bit average and is only pretty good and strong on this meta because of her spell shield but I much rather have her go from a typical kind of adc into this monster of a split pusher than an adc in team fights. Like her w has less base damage but bonus damage to minions and towers as well as it can bounce off a minion or champion and hit a tower. Also maybe because of how much she loves money, she could maybe reduce her stats on her ult a little to gain bonus damage based on how much gold will be granted (not including cull bonus but maybe she would have a little saying about it if she doesn't already) or her passive can change from a rage type of passive to Sivir gains bonus damage to champions on a killing spree or Cannon minion based on the % increased gold amount So she really would be a bandit thay focuses down money rather than victory.
