Another suggestion I would have is to take the Kato JNR 2-6-0 and "Americanize" it, or should I say "Canadianize" it by first, removing the front pilot, which will give you room to put in a 4 wheel front truck, or you can leave it 2 wheels if you want a Mogul.
Then purchase a front pilot assembly from Microtrains and it is long enough to stick out front to accommodate your new front wheels.
The boiler looks right on, and you may have to fabricate a tender from either Model Power or from another one of Kato's steam models.
