Apparantly when the idea of putting gas turbinesin the S58 was first mooted Westlands wanted to reverse the position of cockpit and engine similar to the S62. They had previous proposed a turbine powered version of the S56, which had the engines mounted on pods either side of the gearbox.
The reaction from the military was that an engine/gearbox mounted above the cabin was too dangerous in a crash and so they had to stick with inclined engines in the nose.
