Used your basic idea on the "kitchen" side of the wardrobe, modifying things a bit to make a deeper shelf for the microwave (pics posted elsewhere). So Thank You very much for the idea
I was going to use your idea for the TV, when I stumbled onto something else entirely: folding shelves that are "over-the-door". They fit perfectly on the bathroom wall, and with two shelf heights I plan to watch TV with the set on the lower shelf (upper shelf folded) and then either move it to the upper or put it away when going to sleep, and leaving the upper shelf available for a clock or whatever else.
