I ended up completing my mission last night, and I came pretty close to what you described, Lleechef. It was a lot easier than I thought -- who knew Mom made things look harder than they actually were -- she was milking it!
Made my broth exactly as you described, but as I kept adding "stuff", I did not seem to have enough broth. This was especially true after I added the orzo. So, the bulk of my stock came from the chicken, but I had to cheat a little to add some to the end. I used the grated romano/parmesan blend that they sell in the green can, and used a pepper blend and an italian garlic blend to flavor. The stock had vegetables, but not the final soup -- seemed like there was enough stuff happening in there.
I don't know that I will ever be able to duplicate this feat as I used "a little" of this and "some" of that -- just like Mom would have -- but this iteration turned out pretty OK.
