Convert an old stove into a RMH?

Hello friends.
I have this old oven which works great, and I would want to have more efficiency. I am very curious about RMH and I like them a lot. However start from zero to build one means also throw away this antique object which I also like.
Do you think I would have success ? I hope my fast sketch is understandable.

Paolo, where are you located?

Dear Stamax Antone

Thank you for your reply! I will have a better look at your link as soon as I go back home. Looks very interesting project...
I am now in Tokyo but next year I will move again to my hometown, where that stove is, located in Italy. It's 9 km from Cremona, or 80 km far from Milan.

Allora, Paolo, benvenuto qua.  Io, sono Francese, sulla frontiera, a 15 chilometri piu o meno. Verso gli siti olimpici. Un po lontano da lei.

English translation.

So Paolo, welcome here. I am French, but i live 15 kilometers from the Italian border, more or less. Still a fair bit from you!

Dear Satamax:

We are a bit far between us, but closer than who are in U.S.A!
I've seen the link with your project and definitely hats off to you! Conplimenti!
As you probably suppose, I am new in fire projects and I need to learn a lot. I read a bit Ianto's book and several post you wrote, so I feel I am starting understanding. Just starting...
I know now that my project is not possible as I though. I have to modify concept, materials, and layout.

I will let you know better.
I will study more.

(I can't write in French, and I wrote now in English for respect to others... Thank you for your welcome in Italian. Frankly speaking I was born in Argentina, so my mother tongue is Spanish)
