I think Burton is not in the "high leverage role" right now. I think Lincoln and Mercker have passed him. Right or wrong, Burton is in the "prove to me you've got it together by succeeding in the role that I use you in and that will be multi innings when we're behind" role. I think he did a good job in regaining his spot last night.
If you are suggesting that Hatte was the next option behind the plate, I'm for it. Let him start there against RH pitchers at home. It shouldn't be a huge load for him, it will keep his bat fresh without having to sit Votto and it avoids the carnage of Ross, Javy or Bako playing once in a while.
