JR, need new ideas for modified fictional shortline engines?

[MeowRailroad]

I modified this picture of a CSX C30-7 to be a fictional semi-booster engine that has a cab not designed for use in controlling trains, but just for use moving it around engine terminals. A shortline could probably buy a cheap C30-7 and use it for this, thus freeing up engines with better cabs for use in switching or leading trains.

Notice the blanked-over cab windows and B stencil.
