How about a fork?
One fell swoop, and the n2 comes back, the ninjamine is locked pending contingencies, the Steemit account fights abuse, and everybody gets their coins doubled.
Bare in mind that there are more witnesses outside the top 20 than in it, and the possibility of a certain few running rpc nodes for cash is a real thing.
We only lack assurances that we can get listed on the exchanges, which may not come until after the fork is stable, anyway.
With all the ned delegations out of the pool everybody's vote value goes up, too.
