That's not a bad idea. I like how it gives them space to move around on the top frames. I was just talking to my sorta local, within an hour, beeguy over the weekend to make sure I'm setting it up right for the winter. He told me to put the mt. Camp in like a 2" shim, then the inner cover notch down, then another little shim with a piece of thick styrofoam, then the outer cover. I wonder if you could do the basket, then some burlap and shavings to fill the rest gap, then inner cover, etc? I like it. I think I'll build one. What size wire did you use?...hey, you could even make a little pillow type contraption with the shavings so it would be easy to lift off and check and replace sugar if needed, and then cover it all right back up...I like it! lol
