1 - a ninety days wait period would be very acceptable and pretty sure that would be a shoo in for implementation.
2 - Not sure removing them entirely would go through, but a decaying one has been visited quite a bit. This would also fall in to number 3 with the renewal being necessary as a vote reaches decay maturity.
3 - (4) The veto is a great idea, but not sure it would work. It would almost have to be like a whole new committee voted in by the community, similar to how witnesses are voted in maybe. I would not suggest any consensus witness be allowed on the board though as it would be a conflict of interest.
4 - (5) Since it is a current 'top 20' model, I think you're on to something. I like the idea of percentage weighted voting. I'm going to throw 6 out there declining to 50% on the sixth. I also like the 8 and 25 top for consensus. The numbers would dictate, that no person should be able to vote on more than one third of the consensus. That would truly represent the ooverall view of the community.
5 - (6) The flags. Was against the free ones from the get go. Just going back to it drawing from a single pool, combined with your upvotes, would significantly improve morale. People would be more selective instead of handing them out like crap candy. Communities like @steemcleaners could have an entirely different function and by design, that notification system sounds great to help them out!
Great post man, put some serious thought into this.
Yes the decaying vote I have heard a couple of talks on. BUT! nothing happened. You have to wonder why?
The veto thing would have to be discussed in detail and also I think work best as a paid position that the chain would have to cover.
Flagging is abused by opinion and hate for another. It is negative and will turn new comers away.
