It seems like perfect case to make multi-container encryption as default. That is different data will be revealed using different key and there is no way of knowing how many containers there are in the blob of data and not possible to prove someone is hiding a key.

Not if the state can access your super secret containers while you access them with your software. Because state backdoor either in hardware or in OS level

You could try but you might find it/you get "disappeared" like Truecrypt.
