Availed of the same grasp of alternate political mechanisms as you discuess, I do not propose any of them. All I am proposing is the equalization of stake undertaking governance of Steem, by eliminating the 30x multiplication of the weight of substantial stake - such as held by Tron now - over governance.
Accurately weighting our skin in the game is all I presently advocate, not replacing it with some other mechanism. It's a simple thing, and confounds potential abusers of the extant system, such as we are demonstrably and existentially threatened by today as a currency and society.
