"But, I don’t want to be one of those that uses “There’s only an ‘inferior’ model available so therefore I can’t model whatever?”. There’s also the late Stan Rydarowicz’s rule of diminishing returns.

Go back and read my last post - NYC (links and photo provided previously) and DL&W. Also IC. Do something about that side sill and those too-shallow hoppers.
Frankly, you're better off using the Ulrich offset triple, which is actually an excellent model of a B&LE 90-ton car. [It differs from the other cars by having more side posts (visible in the offset).]
