ovens in rmh and russian stoves

Has anyone incorporated an oven into rmh design? I honestly cannot think of where to put such a thing...perhaps pulling the heat out of the top of the drum by building a brick box over the drum...slow home heating down but it would bake wouldnt it?

I love wood burning ovens, maybe this is odd of me, but i keep looking from rmh and the wonderful way it burns wood so efficiently, to the russian stove which loses a bit of that efficiency in the burn but gains so much in my head by lowing its footprint on the floor and incorporatings an oven!

an insulated terracotta pot on top of the barrel and a pizza stone works pretty darn well and when not in use you just put it away. if its good terracotta you can also roast and steam in it. just soak the pot in water for the proper amount of time.

There are some example on youTube. I'm not sure if the size/control is mastered yet.
