This mod was offered by Valsan.  It involved replacing the two outboard
engines with JT8D-200 series and hushkitting the center engine.  The
thrust reverser was eliminated from the center engine in the process.
Several of these mods were sold.  Delta may have been a customer.  It
really improved performance.  Valsan has since gotten out of this business
by selling it to someone else (sorry, can't remember who).  Since many
airlines operate both 727s and MD-8X, the engine mix might not have been
too difficult to deal with.
