I suppose I thought your use case was mainly getting alerts and 2FA stuff and wouldn't require replying back so often. But in any case I think proxying is absolutely possible and would b easy to setup, especially on a rooted phone. The first thing that comes to mind is setting up a web frontend, so messages would be forwarded to your s and your wifes phones, and then you would access a web frontend hosted on the phone with the $ simcard with a 'real' number which would send out the reply sent via the web form. Would something like that not work?
