This could possibly be accomplished by using subkeys.
I do not think they are intended to be used that way but it might be

People have talked about having a master (key-)signing key on a secure
machine and exporting subkeys from that key to use on less secure
machines. That way the private key that collects signatures is safe and
it is still possible to sign with a well known key on less secure or
potentially uncontrolled machines (like at work) without risking the
real key.

By using the primary key of an OpenPGP key as master and generating
subkeys for the delegated keys you should get the first level of
delegation, i do not know how to get a second level of delegation this way.
