Seems like something only a person that likes to jury rig stuff will like. If it's a matter of living where you can't possibly obtain the correct stuff, then anything goes. But that's not you is it!

Virtually all threadless stems make it easy to change the bars or swap stems without having to remove stuff from them. I've only seen a very few quill stems in 67 years that allow for easy bar or stem swap. And those were in pictures. Never seen one for real.
