Good luck in finding a solution.
Solution is almost ready, implementation is the phase.
Sincerely good luck. But I believe the idea has already failed before it has started. The miners will never signal their readiness for a hard fork that will kill them. The community would also not want to risk a chain-split.
There exists no such thing as a
miner in bitcoin network, I suppose by
miners you mean
pools, there will be no signaling neither any negotiations, pools are the main target and they are to be extinguished.
How?
I admit it is one of the most sophisticated problems in bitcoin right now, getting rid of pools and transition to a truly decentralized heterogeneous network but you always find it more convenient to face a problem when both it is recognized by most people as a serious problem and there is hope/technology to overcome it.
I think both ASICs and pools have triggered enough hatred and protests again themselves and the ugly face of centralized mining is nothing to be covered by any means, the fact that they've been tolerated that long is a result of the lack of an ultimate solution especially for pools and this is what we should focus on: preparing a solution. The community will decide how and when to adopt it.
