I like making use of its existing qualities --
would that mean burning inside the oven, adding an exhaust pipe/chimney, and using it as heating? or maybe cut an opening in the top as a burner for cooking?
I was thinking a hole in the top, with a "plunger" tube, a piece of 4" flue pipe that extends down into the oven/firebox, stopping 4" off the bottom.
Pipe that into the bottom of an inverted half barrel, sitting on top of the oven, which itself has a plunger pipe leading to a proper chimney.
Seal between the barrel and firebox with cob.
The barrel radiates heat, not unlike the barrel on a rocket stove.
Cook on flat surface of the barrel,or heat firebricks on the upper oven rack for baking.
That's one idea, but you could also just punch a hole in the bottom and direct the exhaust from a tlud or rocket stove onto the bottom of a chunk of steel/stone/ refractory inside the oven.
You probably wouldn't even need a chimney, just prop the oven door open a bit.
I have much crappier oven that I hope to use as the firebox for a boiler, with a tlud inside and a couple of retorts alongside it , or with a tlud below the stove heating the retorts through a hole.
A fire worthy box with a nicely fit hinged door has a lot of possibilities for your average mad tinkerer .
