Asynchronous Encryption with wordlists As I understand it encrypted emails have a high profile (detectable through pgp header / attachment). 

Would it be possible to match the encrypted data with a wordlist to hide the fact that the email contains a encrypted message? 

I know that the other person would need the same list of words for decrypting and the message would be only a bunch of random words, but the fact that its encrypted world be not as obvious for automated scanning.

EDIT: As pointed out I am referring to steganography to hide from traffic analysis.
Yes, this is possible.  It is called steganography and there are many techniques that can be used -- there is an entire literature on the subject.  You might enjoy reading about it.

It still won't stop traffic analysis.
