I love your idea, and you are right. Resteeming is the greatest gesture in appreciating a post. But having it appear in my blog irreversibly is the one thing that makes me not want to do that. And in turn people are not resteeming my posts for the same reason. This feature would help everyone in the long run as most would may upvote, but only resteem if they really see value in a post.
