That's fine for the signature key, although you could also extend its
expiration date. But rotating signature keys is generally no more work
than distributing the extended expiration date, so IMHO you might as
well generate a new one.

But do note well that if you generate a new encryption subkey, you can
no longer use the smartcard to decrypt stuff encrypted to the old
encryption subkey! I'd hate for you to just go ahead and discover you've
just thrown out your only copy of the encryption subkey...

By the way, in my opinion, you should always have a backup of your
encryption subkey if it's on a card, because cards can break.

HTH,

Peter.
