Excellent idea. The sensor looks like a DS18B20 based one (sorry I haven't looked at your code to confirm). If it is, then further to hippy's comment, according to the datasheet they will work down to 3.0V, so putting the 4.7k resistor to 3.3V out (pico pin 36) should be fine, especially with relatively short leads as per picture.
Assuming they are DS18B20 based, then from a cosmetic/practical point of view, you might consider 3pin TO-92 style devices to construct your own sensor in a more convenient style. I have used some to monitor the surface of central heating pipes in cast curved Araldite blocks. They are running from a pico with the pull up 4.7k connected to 3.3V and its been fine, all running from batteries, which doesn't look very practical for you.
Again please forgive me if you have fully dealt with the issue of electrical safety, in particular with how your circuits are powered, and any change needed to earth bonding arrangements etc but it always bears very careful thought.
