From what I understand, you're trying to lower the center of gravity and also lengthen the bed of the trailer to make room for your tool box.
With those two parameters, looking at your trailer, the two thoughts that come to mind are as folllows:
For the front I would sleeve the square tube on the trailer. You could use a smaller size aluminum or steel square tube, or, as you mentioned, you work with wood, cut a piece of wood to fit inside the sloped tube. Put a bolt through the existing hole to lock it in and drill a hole for the quick release. It's up to you to figure out how low you want to drop the front of the trailer.
In the back, I can't really see very well how the rear axle is attached, but I'm guessing that it's pretty much just an axle through a hole. If that's the case, what I'm thinking about is a triangular piece of aluminum, maybe square for more stiffness, that you would mount to the side of the rear frame. You would have to drill perhaps one, two, or three holes in the frame, depending if the aluminum piece is going to rock or not. I would suggest that the aluminum piece be rather thick. At the top of the triangle you would drill a hole to mount the axle. Also, you can move this hole back, giving you more bed length for your tool box.
One other thought, instead of using aluminum, perhaps you could use a significant piece of 5 quarter plywood with large washers to fabricate your triangle.
The purpose I'm trying to illustrate is to lower the bed by changing the rear axle mounting position, and to extending the length of the front quick release position.

Am I making sense?
