No: as soon as one element changes, so will the signature as well as the 
packet's implicit name because both cover the whole packet.

But this is ok: what remains a constant in this picture of moving parts 
is the trust model, for example the key used to sign the packet; or the 
trust in the source from where the hash value of the packet was obtained 
(an example source could be a manifest, which would be signed).
