I think you're trying to use a blender as a personal flotation device.

OpenPGP is not meant to provide deniable communications.  It is
concerned primarily with message confidentiality (encryption) and
message integrity (signing).  Just like blenders blend, PFDs float, and
it's unwise to try and make one do the other's job, I think it's unwise
to crowbar OpenPGP into being a deniable protocol.
