The problem is, how do you measure that? There are a bunch of good ideas that most people will agree provide a benefit, but it's really hard to come up with an objective measure of how much money that makes or saves.
That would be far from perfect, there will be free loaders, and most likely than not it will be slightly unfair to everyone. But at least you have removed the perverse incentive to sabotage coworkers in order to look yourself better.
For example: you write an algorithm in your spare time that more efficiently packs together a good that your company produces, such that shipments take up 10% less volume thus saving ~10% on shipping.
