Here's an updated version of the frame. The let-in ledger makes a lot of sense for the peak of the lower roof. I extended the gable end overhangs a bit too as the roof on our house has very deep overhangs and a 4/12 pitch, so I will not deviate too far from the house style.

We will be felling trees for the beams on the 24th in Toledo, OH, if anyone wants to come sling a chainsaw for a few hours. We'll pick another weekend to bring in a sawyer to cut the beams. If anyone wants to bring logs to cut up, let me know and we can help defray the cost.
