I agree, there is great value in sign languages for people who are unable to speak. (Disclaimer: I am hearing and learnt New Zealand Sign Language)
Obviously, it comes with great effort on both the part of the wife and OP, plus a rethinking of some social interactions and even social groups.
However, no problem is insurmountable with sufficient assistance and support from friends, family, and expert groups. Learning sign language is fun and a great way to meet new friends, hearing and Deaf alike.
It may be a last resort, but it's an option not to be ignored.
