Nope... The object model is as follows...
One application can contain one or more Workbooks
One Workbook can contain one or more Worksheets
One Worksheet can contain one or more Ranges...

No exceptions. Why were you wanting a workbook to contain another workbook
instead of just adding more sheets to the existing book?
