You seem well versed in the oven probes...
I've got an older oven that I just got for free for my new house. The oven I had in the previous place seemed to work just like the one you modified and I did the same modification with ease. This new oven has a probe where the "wire" coming off of it is just a steel wire. Much like bailing wire, but thicker. I'm kinda unsure on how I could do a similar oven mod with this setup, but I figure it has to be possible. Same concept, just trick the oven into thinking it is cooler.
