This proposal is as realistic as the animated household goods in Disney’s “Beauty and the Beast.” Nobody’s going to put the money into developing this for the elderly.

The best outcome for most would be a kind, nurturing Christian woman from the Philippines or Central America. At worst, you’ll get a Rachel Jeantel.
Yikes!
