I don't see why that wouldn't work as long as you work out the boundaries that the three of you would have. Anything is possible. For us it takes creating some boundaries and plans knowing that things could change. Most often than not it is just anxiety around what could be rather than what is at the time. Easy does it. Have a really good talk about the details, make sure everyone is getting their needs met, knows that is expected and that no one has any assumptions of how it will play out. Go over some unforeseeable scenarios and then go for it, knowing that stuff comes up and that you will all need to be patient with each other and check in regularly.
