I agree with Techguy on this. One of the most important tenets of DBing is authenticity. We are so connected to our spouses that we know when something is not authentic. I think it would be difficult for you to pull off, but more importantly, you would be eliciting a false reaction from your W.
I mean, obviously, her reaction would be genuine, but it would be a genuine reation to a false situation and I am not sure that you would get the benefit you seek.
