HO NS top Gons and Somerset Railroad cars

Is there any way to make a NS Top Gon in HO? Also, does anyone know what types of gondolas the Somerset Railroad has besides BethGons and Thrall 50 footers? (if any)

You would almost need to buy a NS coal car and then somehow paint top gon on it i have yet too see a manufactur who make them, cause ns converted them to begin with.

NS used old coal cars and rebuiltthemin their roanoke,va shops. i believe its pentrex that has a video titledworkin on the railroad and showed this rebuildproject. the cars are silver with black lettering

So should I hack up some Bowser 45’ NS cars? Or go for the undecs? (If this would even work)
