I think I'd be happier with one less level:
one or more workspaces (context and header)
... has one or more pages (tab)
... has one or more regions (area on page)
... has zero or more widgets
Though reading down I think we may mean the same thing :-)

For moving between pages within a workspace, there is the existing tabbed
navigation model. I think adding a context-switching navigation for moving
between workspaces would fit well; and associating this navigation with the
header also makes sense.
(I find the Liferay model for handling the workspace/pages concept really
confusing, so simpler would be better...)
