New Champion Based off of GOLD MECHANIC

I have a new Champion concept. GILDA :The Ogre Robber Baroness. She would be a take off of the treasure goblins or robber hobbits from Diablo/Golden Axe(remember those guys?) Instead of just pummeling them for gold, you play as her and fight back, Increasing in strength with UNSPENT gold. Passive: Money is Power Gold currently held in Gilda's possession increases her attributes both offensive and defensive by (x%) per 100 gold capping at (-). However, if killed Gilda loses (%) of her gold on death and leaves it on the ground and can be collected by the next champion to pass over it. Q: Gold Rush Active: Gilda starts to run hemorrhaging gold but begins to sprint increasing speed by (x). Reactive: Gilda also is charging up a slamming coin purse attack increased by the amount of collected gold in the purse divided by .1% W:Gimme Your Money! Passive:Gilda slaps 15 gold out of her opponent every third attack which lands, randomly, nearby. Active: Gilda swings her purse, knocking champions back a short distance back, hemorrhaging (30) gold and knocking (30) gold out of any champions struck and doing damage according to Gilda's collected gold divided by .3%. E: Money Shot Gilda throws a fist full of gold by skill shot. This does 100 +( Ad/AP) damage and increases range per second charged, up to 3 seconds. R: Gold Crash Gilda leaps into the air and slams the ground knocking ALL champions into the air and causing (X)Gold to be knocked out of all champions hit and randomly spreading it over the area hit.

I love the idea of being able to play as a treasure Goblin on steroids. However, I feel like balancing a champion like this might be a nightmare. I really hope the idea is considered. She would be extremely entertaining and interesting to have on a team. If protected she could be very dangerous. If bullied she could really feed. Hope you enjoyed the idea, let me know what you think!
