Increase Each Vote's Impact
It may seem minor but I think it would be wiser to do one thing at a time. Increasing per-vote power is directly related with the reward curve (if there will be any curve) and doing both at once would be turning two knobs on the same thing and expecting a useful experimental measurement.
Personally I'm not convinced linear is the way to go but as I asked in my other comment, I'd like to hear the "why" part first before getting into that.
