So how do I recover with both SD and TM?

[box]

I read the articles covering the coexistence of TimeMachine and SuperDuper.
What I did not find was a description of System recovery with both apps involved.
I use SuperDuper alongside with TimeMachine. Lets assume I update the SuperDuper clone every... err, 2 weeks, maybe less.
So when a great catastrophic disc failure occurs, I will switch to my backup drive and continue working with the external drive.
Since the data on the cloned drive might be out-dated, I would have to update to the latest state with TimeMachine, then.

Since I do NOT want to make a total system recovery with TM, which would require the System DVD and hours of waiting, I expect to find the TM space, choose for example my personal home folder and click restore.
So the question is: will TM properly operate with the clone from another drive, and even from another time, as a destination to restore?

I just want to get this together. Because if this method would not work, I'd have to use SD very frequently - and in this case TM would be quite useless for me.
