Phew! I bet there isn't a way back, I've had many a similar experience and the time to fiddle around isn't worth it with a clone sitting there IMHO. Just clone back and start over.
Even a Time Machine restore maybe be slower than cloning. You could try TM on just the system folders (or even dragging from clone) but it maybe a real mess and you'd need to boot from an alt boot partition.
But hey, it's fun
I'd be fine with a TM restore.....but I'll be going back in history. I want to keep my current apps, my currents docs etc... I suppose I could move them to my raid array, but I wonder if that will impact my registrations/activations on them when I move back to the fresh OS....
