Well though out and presented. However, the one area I split with you, like many, is that Baltimore in Baltimore is far from a dream scenario. In fact, I would place that under more of a nightmare scenario. Worst possible outcome type thing. That team playing at home plays on another level. It really doesn't matter that Buffalo has beaten Baltimore twice in the playoffs. Those teams are not this team.
In fact, I would put the Bills getting the 6 seed as a better spot. Likely playing either Jacksonville or Indy. Then with a win, we would likely head to whoever the 1 seed is (Denver or Patriots).
