Refreshing private key

Hello,
is there is a need keeping old key id, you can generate new subkeys for A/S/E, keeping the old 2048bit certification key C only for offline signing.

Keystructure:
Mainkey with old ID 2048bit
- - Subkey A 8096bit
- - Subkey S 8096bit (beware of this, long signature...)
- - Subkey E 8096bit

Old subkeys can be deactivated/revoked or not, GPG will use latest keys generated.

Generating keys > 4096bit can be done with GnuPG-Pack up to 50176bit (RSA) with some additional features:

Beware of compatibility with standard gpg installations!
Security advantage isn't as great as it seems to be...

Regards, Chris
