I'm glad you're not chopping up the body and found a prototypical alternate solution. FXD chips easily if you're not careful, tough to have it do what you want.
I was already well aware that it would be likely to damage the kit, which is why I was hesitant. I think I will stick with my original plan of using the Atlas 42' gondola to attempt to kitbash some of the pulpwood conversions, despite the fact that it would be inaccurate. They are also much cheaper if I screw up!..Though, if you ever wanted to pursue the pulpwood version(I can dream, right?), I would buy many, many of them..
