That would not work, the intrinsic problem is that they control huge amount of money, and since they sit at the top of the pack they take the largest share, no matter their relative contribution. That's pure animal instinct and that will not change unless you use fear of god or something similar to have them behave.
What would they do ? Hollywood accounting: all the non management worker in a fully-owned subsidiary making shiton of losses because of the cost of contracting the boss from the parent company. Or they would force everybody to be an independent contractor. Unless we get back into full-employement economy, they can basically do whatever they want to work around that problem.
To really solve it you need to work on the actual problem: make the market tougher. Free market is a legal construct where companies fights, you can make it as tough as you want. As long as the rule are fair, competition will still play. For example increase the administrative overload for large group to tremendous level and smaller, leaner companies will take over.
Secondly, you want to change subtly people mentality. People would find it weird for to give the medals and money to the team coach rather than the actual player. Well, with a few exception, everywhere else that is considered normal.
