This may be OT and badly so, but it reminded me of going to brunch with a friend of mine who is single, childless and Eastern European with notorious intimacy issues. I was lamenting dS2's sleep and she said when she was two months old, her dad shut her nursery door and forbade her mother from going in until the morning, and she suggested that as an option. It just made me laugh.
You know, I was never comfortable with CIO techniques and my accidental use of them when ill failed miserably but I know great parents of all persuasions with happy well adjusted kids. I agree in listening to your gut - if you don't feel comfortable there is probably a reason why. But if it feels like the right choice, give it a try and stop if it begins to feel wrong.
