I've done it for a rescue CD I hacked together based on an existing
MacOS Rescue CD for my OldWorld. Apple's CD was too small (300MB) for
the task :-)

As Brad explained, apparently not. But I'd expect that if you create a
new partition map, and 'merge' old and new, keeping driver partitions at
the same place, then that should be OK. Or create the new partition map
with a tool like Apple's HD-SC Setup (the patched one), or the Micronet
utility, to name those I remember. Although, that would probably mean
running your old disk for some time....
