Can somebody give me advice on moving to stacked branches?

I think that the feature you are looking for is called "nested trees" 
rather than stacked branches.  "Stacked branches" in Bazaar refer to 
branches some of whose history is stored in another branch.  I think of 
this as nesting (or grafting) in the "time" dimension.  What you appear 
to be looking for is grafting in the "space" dimension, within a 
directory tree.  This sort of embedding between branches is called 
Nested Trees in Bazaar and is a feature that is currently under 
construction.  See http://bazaar-vcs.org/NestedTrees and the pages 
linked there for more information.
