RVnut, as to putting the same TV bracket in the bedroom as the Kitchen, I think the problem you'll run into is the height on that bracket, I don't think it would fit with the existing framing. The things with cutting a new door and using a piano hinge was no messing all all with the existing framing. I used the magnet catches at first to hold the door shut, but out of an abundance of safety added a physical latch as well. So if being tightly secure and safety is your concern, there are a number of latches that you could use.
