That's certainly thinking outside the box!
Couple reasons I don't think it will work.
1st) I don't think it can stand the thermal shock of instant high heat, I think it would quickly crack.
2nd) You want your riser to flow heat quickly and efficiently. Turbulence in the flame itself is OK , forced corners would just slow it down.
3rd) Personal preference here ... In my opinion, it's literally butt ugly... who would want a toilet in their wood stove ?
4th) Don't let my opinion stop you. If you think it will work then give it a try! Innovation is the Mother of invention !
I will happily check out your photo's & post, if you build such a thing.... but...even if it works super dooper good ... I don't think I would want one.
Kind of off topic but I am pretty sure I am the only one alive whose ever had his hand shredded by an exploding toilet.
What happened is, I needed to do some work behind the toilet, so I undid it, and for a lack of a better place, stuck it outside for a few days. It was spring so there was some warm and cold cycles as it sat outside.
So a few days go by, and I decided to install it again, and haul it back in. I hook up the pipes and turn on the valve...
What happened is, the water inside had half froze, so when I turned the water on, it acted as a water hammer, and the ice inside shattered the toilet. With my hand right there, the super sharp ceramic shards shredded my hands from the porcelain shrapnel.
As I said, I am probably one of few people who can lay claim to this incident.

I consider that extremely relevant. Wow. Important to know if one is considering innovating with commodes.
Somehow I have lived an interesting life without really trying. "Hey, has anyone shredded their hand from an exploding toilet? If you have, raise your shredded, bandaged hand." (Travis hears nothing but crickets. BIG crickets)
well those thoughts certainly give me pause... esp. the exploding bit! I was thinking maybe upside down, with the double walls acting as the gasification chamber. As it is already fired in production I thought it could handle the heat. If I try it I'll document and share...

The problem with using something ceramic is not that it cant handle the heat, it's that it can't handle differntial heating. Some parts will be hotter than others and expand at a different rate. If you are lucky it will crack, unlucky it'll explode.
I can speak from experience that it won't take the heat. I had a wwoofer here who tried using one as a grill for cooking food. Put the wood in the bowl and he figured the air would come up through the bottom. Wallah, perfect fire. Before he even got the grill in place, the toilet cracked. But he did persist and manage to cook one meal. It's a shame that old toilet bowls can't be converted to outdoor cookers.
It's never too late to start! I retired to homestead on the slopes of Mauna Loa, an active volcano. I relate snippets of my endeavor on my blog : www.kaufarmer.blogspot.com
