Lloyd, I think a very simple solution into this direction is Crispin's Vesto-Stove with braai-plate. I only know this from the web, but find it excellent. The overflow of fat is burnt immediately during the roasting-process. -And I think, after bbq, the burning wood could be quenched to stop, to get the biochar.
By the way: The Indian method of T-Lud-cooking to make charcoal and the possibility then in a second step to burn the charcoal (or better, only a part of that!) in a Sarai-cooker (which I would like to call a simmer-cooker) is a good alternative, to only use charcoal as biochar. I think there are few stoves, able to simmer in a moderate fuel-consuming way, if they are not specialized to that job. -And the Sarai-cooker seems to do that with only one or two charcoal-briquetts for a long time.
