Right you are, I was thinking of the depth of the side pieces, not the thickness of the edge pieces.
Doing that could be fine for making more space at the bottom. It won’t fix how the gap is too big at the top. But if OP doesn’t mind, then no biggie.
Whatever you do, don’t take it to an airport, courthouse or a bank… Oh you’re in Canada. Never mind, you guys don’t have the police looking at kills like a video game score up there.
