I'll answer a few of these questions quickly.
Canthopexy? Not a good procedure for you. This is a component of a larger procedure typically that is designed for reconstructive purposes. It is over used and over average sized and young people and often offers very little results and at worst bad scarring and bad outcomes.
Brow bone shaving is really meant for someone who is well versed in cranial facial surgery and performs fascial contouring by altering the shape of the brow bone cheekbone jawbone etc. frequently. I cannot tell you if this is beneficial to you from her photographs.
I'm not quite sure where your fat grafting would be done. I am a fan of fat grafting and I uses frequently but the reports that U here about uneven results or fat that goes away are not false. Fat grafting does have some significant variability and it and is best left to more experienced hands.
Sorry I could not be of more help
