One thing to keep top of mind in this discussion is that the bars are sacrificial. Meant to be damaged or even destroyed in the event of a crash. Their function is to first protect the rider then the bike. The hard part is making them look good doing it. If they fail in their function do to weak points then form is irrelevant.
Exactly this! This is one reason I've strayed away from quick-releases in the past. It just seems like it reduces the strength too much, which then makes the bars pointless. Although, we used a variation of a slip joint on our GSXR Canyon Cage that I believe may come in useful when designing a quick-release mechanism. This is something I'm going to look into more once I get the bike in our facility.
However, it's funny that you mentioned the bars being sacrificial because I was just thinking about this earlier. If we could somehow get a quick-release bar to work, all you'd need to replace in case of an incident is that single outer bar that took the hit.
The hardware and base mounting plates/equipment would more than likely be okay to reuse, whereas the outside bar would need to be replaced. So, this would at least stop you from having to purchase an entirely new set if you did go down and would help keep repair costs on the low side.
