No.
The key word in your question was "simply". Converting that door to a push button handle door requires a lot of cutting, fabrication, and welding. Original doors are hard enough to make work correctly. It is not something I would try to do, and I have done some pretty creative things.
If your pull down handle door has a vent window, it is a '51 door. They were a one year only door making them scarce. You should have no trouble finding a buyer for it, then you can buy a more correct door for the '54.
'52 through 55.1 will work. The '52-'53 use different fasteners to hold the cardboard door panels on, but that is very easy to accommodate.
