rocket stove for cooking inside

So glad to find such discussion on Rocket Stoves!
I've been cooking on this little rocket stove (not for mass or water heating- just a small design make for cooking) for years and I want to adapt it to be able to cook inside the house. I may need to make a new one with a better ash collecting system.
This means adding a chimney for the exhaust after a spot for the cooking pot to fit neatly in.  Basically I want to enclose the cooking area with cob and vent the exhaust through a hole in the wall.  I actually designed my house with a hole in the wall expecting that someday I would get to this.
Anyone tried this? Seen this?
