Any opening,roll down rear windows around?

Ok so crazy idea #32105. I had an 06 tundra with the power rear window and ever since then I have wanted that feature in every truck I drive, I was thinking of maybe trying to use a power sunroof as a rear window in my small window 63....has it been done?

Thinking was I would cut a flange from donor car maybe 2" all around and weld that into opening on cab then line up the mechanism on inside rear cab wall and make mounts for it. I should note I will not have the tank in cab no matter what.

Simpler approach would be one of the little manual ones that you just tip up at rear in stock form so it would tip from bottom in truck.
