A couple of honest questions:
1.  What happens to indexes, triggers, and other dependent objects  with schema swapping?  You may not want an index on the table in the shadow schema, but you probably will want that index in the active reporting schema.  Does the index in the dbo schema need to be rebuilt when the updated table is swapped in?
2.  Is there any benefit to setting this up in a SSIS package rather than doing the schema swap as a Transact-SQL job step?
3.  Technet specifies that "All permissions associated with the securable that is being transferred are dropped when it is moved."  So it sounds like you would have to set up steps in your ETL to restore any object specific permissions?
