Interactable Block Entities in Sulfur Cubes

I think that being able to interact with the blocks inside Sulfur Cubes would be revolutionary as well as being the most "minecraft-y" implementation of such an idea. Maybe not every block entity as some wouldn't make sense, but if you could put a Crafting Table in a Sulfur Cube for portable crafting that would be very cool. Just right click it as though it were a normal Crafting Table and the interface would work as normally. Or Furnaces for portable smelting, Jukeboxes for portable music, Brewing Stands, Ender Chests, etc. But the what would probably be the biggest use case would be Chests/Barrels/Shulker Boxes. Being able to have a Chest that can hop behind you and hold all your items would be fantastic help for on-the-go item management and transportation. And being able to load up a Happy Ghast with an entire base's worth of leashed Chests would make moving a cinch. They would be a cute and fun early game alternative to Skulker Boxes, and their implementation wouldn't be balance warping since you can already accomplish similar things with Chest Boats and Donkeys. Given the recent changes to have TNT Sulfur Cubes explode this feels like the logical next step as well as another potential use case for Sulfur Cubes to make them even more interesting.
