I have to say, I find some tension, even contradiction, between speaking of moving to a decentralized model, and then turning right around and suggesting we move to a handful of committees to manage all this public Steem Power and mined Steem.

Which is it? Decentralized? Or just moving the central repository of power from Ned to other people?

And how will the elections go? Is it going to be true democracy, in the form of "1 person, 1 vote", which obviously runs into the issue of bots and multiple accounts, or will it be like the Witnesses situation, where your SP allows you to have more say in who gets elected?

In which case, again, more centralization, rather than less. Currently we have the whales and Steemit. Under this proposed system, we'll give the whales the keys to the kingdom.

That is, honestly, more centralization, not less.

I strongly recommend inviting some people who are not invested in Steemit to both help run the system, and to help design a better system. Those people will be unbiased, and be able to make good suggestions. Otherwise, what I'm seeing is, the people with the power making sure they end up with more of it. Yes, you invested in the system, but you're not the only one who have. Outside board-members are a good thing to have.
