Making the assumption that the footwear that has survived to become part of museum collections may be because it didn’t fit well, wasn’t a favorite pair, didn’t look like the wearer wanted, in short was a dog left sitting at the bottom of a closet, I feel that one could get creative about the detailing using the survivors as a starting point. This was also not a period of mass production and I would expect that there was a lot of individuality exercised. If you are inspired, go for it.
