 Only plane that comes to mind is the DeHavilland -7 although it's not
 really a *small* plane but it is a 4 engine high wing turboprop.
C-27 Spartan?
C-123 Provider?
Unfortunately both are both two engine planes - but they do look a little
like smallish C-130's.
And in the two engine vein, the deHavilland Buffalo looks way more like a
Herc than a Dash-7 does.  However, none of these match the original
poster's mention of "proposed to build the production aircraft in Puerto
Rico".
