Looking at the prototype and the model there are a number of characteristic detail differences. Also the wheelbase looks a little longer in the model and the saddle tank needs to be flatter on top. However, I would say if the cab was completely rebuilt with rectangular windows, the safety valves replaced with Ross Pop valves and the sandboxes put above the running board you would get a fairly convincing representation of the T&CR loco.
The smokebox is a little far back as well though depending on how much surgery you want to do to it,I would leave it, but if you did modify it you could change the buffers as well.
