Yes, of course. Here are three versions (with a bit of cheating to fill a rather unfortunate gap between the garlands and the upside down upper element):
I do like the impression that the two garlands in the centre seem to start with the diamonds inside the upper scrolls. And the upside down scrolls look rather like a closure of the design than the beginning of a new tier.
Still, I think I'm with Beth on this one. The upper frame of the original design was exactly that: a strong frame for an otherwise rather busy structure of elements which are all quite weak and not really distinctive enough for a tiara of this size.
