I actually think thats a really horrible concept. I mean what exactly is the aim?
Essentially you are relieving your actual identity. If you crave the fact that you keep no secrets from each other, then just give your partner your password or something. But dont make your friends talk to you as if you are one person. You had lives before each other and you will continue to have separate lives if you split up. You are not, like, one entity. It's just really over the top to do that.
