So I wasn't happy with attempt #1, not happy at all. Ok it was a fail, but I was on the right track, so I scoured the internet looking for something better.
Found these 3m Command mini hook's, and used JB Weld plasticweld epoxy putty to sculpt things to fit.
I used scotch tape on the bracket as a bond breaker so the plasticweld wouldn't stick to it. Mixed up some epoxy putty and worked in. After 3 hrs. cure time I was able to file and tune the plasticweld.
3m removable tape thingy.
Removed the dual lock industrial velcro and installed the new set up.
The UG bracket slips on the hook just like it would on a UG attachment system.
This work's much much better, a light press on the corner of the UG activates the button's nicely.
The 3 button contact point's on the mirror are a small and medium self adhesive rubber drawer bumpers stacked up.
