I think it is possible to use an old DVD (such as a test preview disk)
as one of the repositories for jigdo. Then you only need to download
component rpms that are newer than what is on the DVD.

In theory, you could use this process to get increasingly more recent
test DVDs, using the last test DVD as a repository. You only need to
download the changes. Would speed up the Test-Change-Test cycle too.
