This doesn't work because a large-scale miner can trivially make themselves look like a very large number of much smaller scale miners. Their ability to minimize variance comes from the cumulative totals they control so 10 pools of 1% of the network cumulatively have the same variance as 1 pool with 10% of the network. It's also very easy for miners to relay blocks via different addresses and the cost is minimal. The biggest cost would be in DDoS prevention and a miner that actually split their pool into lots of small fragments would actually give themselves the ability to do quite a lot of DDoS mitigation anyway. If no-one is doing this right now it's simply because they've not had the right incentives to make it worthwhile; if the incentives make it worthwhile then this is pretty trivial to do.
This is one area where anonymity on behalf of transaction validators and block makers essentially makes it pretty-much impossible to maintain any sort of sanctions against antisocial behaviour.
