That is actually a more sound proposal. Placing limits on votes that overlap with wales per week is a great idea.
I just believe that rewarding Curation is a must to give incentive to people and new users to join and use steem-it on a regular basis.
Plus, for me as a user with little steem power, making our vote count will give us incentive to be more engaged and evaluate content properly.

I dont know if all this made sense :)
