After reading that note four times, I still see no details about your
attack tool.

Your note does not contain the word “timestamp”.

According to RFC 4880, the key generation timestamp is near the
beginning of the key blob.  Thus, every time you change the timestamp,
you need to re-hash a relatively long fixed string (the public modulus
in an RSA key, or the group parameters in a DLP-based key).  Changing
the timestamp may be useful for DSA or ElGamal keys (I'm not convinced
of that), but it's not helpful in generating an RSA key with chosen
key ID.
