Yes, it is a viable swap, I did this on a '54 Super, and I'm happy with it. I did it with original suspension, spindles and hubs, but added Roadmaster brake plates and shoes for the wider 2.5 inch brake surface. WMS to WMN - and I guess that means "wheel-mount surface" - less a half inch difference from stock.
Only caution you might check, you will need longer front lug bolts from 1958 and later to accommodate the thicker aluminum drum face. They are marked "F" for "front."
I imagine they did something similar on your car.
