I think that would really oversimplify the benefit of water changes. When I do water changes I want to do two things: take stuff I don't want out and put stuff I do want in. I take out much more stuff than just Nitrates and what I put back in with the new water has nothing to do with the pellets. I don't think adding pellets = fewer water changes is a good equation IMO
