Would it not simply be easier if you choose an image format which
support your needs?

In your case choosing Qcow2 as image format for your VMs seems
appropriate since this will give you the choice of doing snapshots of
your VMs before doing any changes and the decide after your changes
whether to rollback the changes or delete the snapshot.
