I'm afraid what you're suggesting isn't really possible due to the way Minecraft servers work. They control which actions can happen on their side, like viewing and taking items from chests, and we can't change that.
Also, I've noticed this thread might be a duplicate of a previous one we had on the same topic. You might want to refer to this thread first: https://wurstforum.net/d/166-chest-in-server
Thanks for your suggestion though!
