hi, I had suggested the same for an encryption product called digisecret,this is what they had to say.

Here is an example where hiding cipher text in cipher text is ideal..

DigiSecret currently does not use assymmetric algorithms. Besides this the introduction of this technique will mean that the secret police will also know about this fact, so the person's harrowing experience with the secret police will just be doubled: first they will obtain the fake password and then the real one. Also it would not be hard to track it on the algorithm diciphering level and to understand that the message is not real.
