Solution for jumbo pack Steelbooks (like Up/Monsters)?

The hubs would hit if you put two doubles together. It may not close right, and even if it did, it would cause the discs to release from the hub, so you could end up with a floating disc(s).

The hubs must be offset and there isn't enough room in a Blu-ray case for four discs.

Now, if they would switch to a 8cm disc for the digital copies, I believe they could get four in a case. A DVD2 would have enough space to hold any of the digital copies released to date, so a DVD5 is total overkill. A DVD2 would need less plastic to manufacture, result in less waste when it ends up at the dump, just better all around.
