That would be a posible implementation of a "REDPOS", this some of my comments from the original post

Maybe a good REDPOS implementation could use the account-age (or the entire REP) as a parameter affecting not only the eligibility of an account, but the voting power of every account.

If "NEWSTEEM" would run in such a REDPOS, then NEWSTEEM holders would increase or decrease their voting power not only by means of SP, but by means of SP affected by their own REP. Would not affect ownership rights, since it would be a known attribute of the NEWSTEEM asset class.
