What about doing both? Make your own obfuscated system and use it to
encrypt the well-tested system's ciphertext. Seems to me that this has all
the advantages of both and very few disadvantages. Beware of doing it the
other way around, though, since your system could easily make things less
secure if you used it to encrypt the plain text first (because your method
could introduce some known text into the plaintext).
