If you have a disability you could qualify for the USPS hardship delivery program.
wife is technically disabled but not enough for that problem from the looks of it.
I do like your way of thinking though.
That is supposed to be hard to get and depending on the district is impossible. Mostly because of entitled individuals like those who have handicap placards on their cars, but can still manage to run into the liquor store at a sprint. You must be disabled and unable to get to your box. There must not be someone able-bodied in the household. Your doctor has to fill out some forms.
