That's a splendid idea, and I don't necessarily find it all that strange. I am married within the system myself. If you wish to involve them in some way, you could possibly discuss it with them. And an in-system relationship could certainly work if one interacts with the other partner within the system's world, rather than outside. I have to do that myself - I am a fronter in our system, but my wife does not front, so I have to travel to our own world to do that.
