Hmm, I'm not sure if this is going to help, but:
Remember that to get portrait photos in real life you have to rotate your camera. (or by cropping a landscape photo, but then you wouldn't be able to match it)
Rotating the coronacam 90 degrees instead of switching the height/width in render settings has helped me match some photos in the past. Not sure if this would play well with the perspective match tool, but worth a try? :)
