Anyone modified the giant red brick (6313287) to fit on top of each other?

I have three of these but was disappointed that they can't really be stacked because the bottom is not compatible with the studs on top.

Has anyone made a mod of this to fix this? One idea I'm thinking about is:

1) Inverting the studs on the bottom like this (is there a more secure way now?):

2) Line the bottom edges with panels. I hope the panels are deep enough to seamlessly accept the 2-plate deep studs from the top.

But it's likely the fit will be a bit loose.

I thought about this as well, but haven’t looked into it. There’s an old picture frame set, 40173, that has 2x2 “stacked” on top. That’s probably your best bet for this.

I looked at the instructions for 40173 and the stacked bricks are just for show as the blue/green brick is hollow through to the bottom.

At least lego is consistent as the 2x2 red and blue bricks are the exact same height as my 2x4 brick.

I haven’t looked at my 2x4 since I built it, but I think just removing the top layer & sticking the two together, like the blue & green bricks, is the best solution. Unless you can take out the middle plate of the 2x4 to make the underside deeper?

Yeah, I’m glad they stuck with the same building method. I had my eye on that picture frame before the freebie, solely for the brick builds.

I just realized that the dimensions of some these blocks is slightly off. The scale is x3, so compared to a normal brick, the giant brick would be 3x on width, length, and height. So the expected height is 3 bricks if measuring to the base of the studs on top, but here it's 3 1/3 bricks high (one plate too much). So for the picture frame set, only the blue one is scaled correctly.
