I am afraid you wife will be disappointed.
Lexus when with safety and thought it would not be wise to have the door power open with you standing in front of it. They even include a "beep" and "delay" when you hit the "close" button to give you time to get out of the way.
Only way to power open the rear hatch is to use the fob OR push the button on the dash.
Opening the hatch by hand requires little strength as if you just pull it towards you it will finish opening by itself.
