That is similar to the factory set up, which was a pressure alcohol stove. I removed that stove and dropped in the cookmate version of that Origio 4000 stove. I just had to mount the gimbal weight directly the to bottom of the cookmate and cut the corner of the stove to allow the gimbal lock of the frame to work.
Patrick, without the gimbal frame, I think you will need to custom build something for that stove. Or try to find a gimbal frame from someone parting out another J/30 and then sell that stove and try to get a drop in Cookmate.
Do you have a link to a drop-in cook mate Origo? I can't find information on that anywhere.
