Yes, this is possible. In two ways even.
The list you are looking for is, as has been mentioned,
/etc/setup/installed.db (you can `cut "-d " -f 1 < installed.db`), then you
could call setup.exe with necessary switches to install the set of packages
you want.
If you want to avoid downloading from external servers, you will have to move
your installation cache along with setup binary.
