I could see the creation of “chameleon” PGP systems that when brought up with one passphrase have all the naughty bits, but when brought up with another one have naughty bits permanently erased.

The very first thing the feds always do is make a bit-level copy of the hard drive (by taking the drive out of the machine and putting it on their own equipment). If you then enter an "erase all" pass-phrase which results in changes to the drive, they immediately charge you with obstruction of justice, restore the drive from the backup, and tell you to try again.
