I don't have a problem with the use of the DW as a source of data for other operational systems. If you consider that the data warehouse is where the data will be cleansed, it is the logical place to get data for operational systems. This is the so-called "closing the loop" with data warehousing. In terms of additional DW usage, in whatever form that takes on, the only thing to be wary of is impact on other DW usage (and load cycles, etc.). As long as that is considered, I don't see a problem with the transformation you speak of.
