There are at least 2 hotends besides JPrusa's that are all-metal construction. And if you move away from the one piece design, it should not be extremely difficult to manufacture your own, provided you have access to machine tools.

ptfe should not be used as a support structure, it becomes like jello at high temps, this is why designs that use the ptfe have peek block beneath them, so the peek can support the barrel and keep the ptfe in place.

If you are actively cooling the cold end then using something with low thermal conductivity like PEEK might make less sense. I use aluminum as my cold end and a 40mm video card fan is plenty powerful enough to keep it cool to the touch.
