code for GnuPG that follows this basic design, and it works well.

Will it be possible to convert existing subkeys? AFAICT, putting the 0x19 
signature in an unhashed packet, this should be relatively painless. (Will 
keyservers properly deal with subkeys with the additional packet suddenly 
appearing?)

Yes, it is possible to convert existing subkeys.  One of the reasons I
advocated using a subpacket was for this ability.  Based on a number
of tests, and a conversation with the author of SKS, I don't see any
problem with updating existing subkeys on the PKSD or SKS servers.  I
haven't looked at the LDAP server yet.
