converting a Servel Fridge

I have a very old Servel propane fridge with a burner that is not long for this world, so I want to try and see if I can rocketise it. I have seen a couple of experiments on youtube, but this is a full size deal. Any advice or words of wisdom in regards to converting to a rocket stove burner? The fridge is in OK condition and is on an Island in the middle of a lake ( with lots of wood) and there is only wood heat oil lights and no hydro. Is mini rocket stove power possible?
