Another issue will be the thickness of the new wheels: because the Proto wheels will be considerably thinner than the original ones, the sideframes of the trucks will need to be altered so that their back side is closer to the face of the new wheels. I'm guessing that, with press-in sideframes, this will be easier than the same task for freight cars, where most trucks are one-piece plastic castings. This is one of the reasons why I don't use semi-scale metal wheelsets on my freight cars - the shiny tread just draws attention to the over-width trucks.
I'd also guess that converting a steam loco to Proto-whatever standards would be even more difficult, as the cylinder casting would need to be altered in order to place the side rods and valve gear proportionately closer to the drivers.
