It's certainly a great start but when you get into the weeds, there are a few louver differences.

No doubt. I was just looking for starting points.
I label most of my own kitbashes as "representations" because the rivets/louvers/etc never end up in the right places.
My own similar goal is to produce a H12-44-TS - which is the variant produced for Santa Fe's use at Dearborn station. At first glance, it looks like a later model H16 with a smaller radiator grill. But on closer inspection, it has walkway and louver variations, and for some reason (I am guessing to cram in whatever steam generator ATSF required) is just a bit longer, even though it has a smaller primer mover.
