Use of shulker boxes from inventory

Minecraft has a huge inventory problem and recently I have been playing with a mod that allows you to use Shulker boxes sort of like bundles. Hold right click and drag them over items to pick up, right click drag to remove items, and the ability to view and scroll through individual items to grab. I honestly believe this would go a long way in dealing with the inventory issue, and I don't believe restricting the functionality of shulker box ease to bring any meaningful benefit as it is already an end game item. One pitch I saw that I think is a fair balance if the base was to stay the same is to make it an enchantment. Secondly, I didn't wanna put this in the title since it's not the main idea, but the ability to use and Ender chest in your inventory kind of like a backpack, perhaps and enchantment, pairs so well. Picture this, you need more rockets for your elytra. Currently you have to land, move your ender chest to your hotbar, place it, open it, move your shulker box to your hotbar, place it, open, grab rockets, open end chest, put shulker back, mine end chest. Vs the experience I have with the two simple accessibility mods. While flying hit a keyboard to open the ender chest, pick up the shulker with rockets and right click on the empty slot I need them it, put it back and close inventory. It makes the gameplay so much more smooth without these suddenly stops to do repetitive tasks that just take away from the fun and add to the chore.
