That's a nice idea. And my, what big feet you have!
Your solution made me realize I should share my solution (even though I don't have pictures...)
I simply used two pieces of 1/2" baltic glued together with one cut for the hatch and the other cut for the lip. The leftover piece from the lip was glued to the hatch.
