Did the RSA implementation change significantly in 2.x?

No, it used an own algorithm, BassOmatic, but unfortunately it proved
to be flawed.

Would it? If someone would write GnuPG plugins for the BassOmatic cipher
of pgp 1 and an MD4 hash plugin, would GnuPG then be able to decrypt and
verify pgp 1.0 messages? What I see from the pgp 1 documentation is that
the basic structure (pubkey algo to encrypt session key of symm algo) did
not change since pgp 1.0.
