Forgive a silly question; why do you want older SEP 11 packages?
The SEPM RU2 install source folder contains a folder, "Additional Packages". You can import a SEP 11.0.7000 32 bit client and an older SEP 11 Mac client by browsing to that folder when you choose:
Admin>Install Packages>Client Install Packages>Tasks>Add a Client Install Package...
Would this satisfy your needs?
