In relation to the recently posted drop video in the other thread, you can see that, if the bike continues to go over, the mirrors WILL be taken out (Connie mirrors, particularly the elbow joint inside the rubber sleeve, break easily in falls). In at least one of your drops, you can see the bike fairing kissing the pavement, and note that the bike has no mirrors...
https://www.youtube.com/watch?v=LJ1_KKSb18AI know this from personal experience, and several tipovers. I had millerized pegs on the bike, and this is exactly what happened to me. My left mirror was toast, and my nose fairing suffered damage. One of said drops popped my front turn signal reflector mount (it is taped to the bke now) when the fairing was damaged, and the other side's turn signal lens was punctured in the fall. Quite expensive overall, so I have a lot of gaff tape on the bike currently (gotta luv random drunk people knocking your bike over)...
Mirrors for this bike ARE fairly expensive, not to mention the nose fairing and turn signal lenses... which is why I now have 'customized' mirrors on my bike, which aren't nearly as big (in mirror surface/reflective area) as the regular Connie mirrors were.
I would recommend the following modification to your design (see pic below), to minimize the chance of this happening. The red lines show the angles needed to protect the mirrors, assuming that the top of the front cages is close enough/above's the bike's center of gravity in a tipover. It might not meet
your aesthetic standards, but I think it looks quite stylish...
