Just following up ...
Purchased a mount that folds up and adds very little but it was still too much. What is being overlooked is the thickness of the door sits inside the recessed area and a border around it is what seals it off from the elements when closed. If I would have noticed this I would have known no chance for a different mount unless its one that you cut a hole for to recess it in the wall where current mount is.
This pic proves the point taken with the door closed. Only about an inch:

I think next best option would be one to clamp onto the patio railing and just move the TV over to it but not sure this is really worth it to me. Its easier to just open up the garage door and use the big TV in their instead to watch from ground (I removed my rear patio as loading a wide vehicle).
