This is a super secure way to mount a mirror, lights etc to your Omnium. I'm using any star-nut and a PNW mirror. The hardware from the mirror is the same thread pitch as the star nut.

I could see this being really handy to mounting different things. Just don't do it on the front if you ever want to use your extender bar again.
