I'm the Wiz, and nobody beats me!
Now that's similar to what us Carpenters would have done. A knee brace or other types of braces are the strongest at a 45 degree angle. The top of those plywood braces will have the most force where they are attached to the top of the cleat(?) so make sure they are fastened really good at the top for a pulling outward force. Anywhere else only keeps it from sliding downward.
Glad to hear the damage wasn't too heavy.
