The maintenance >folks would be incredibly irritated by such a monster! 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.
