Adding 16 bits or 32 bits doesn't matter: The networking stack of every device would still need to be updated to understand the new address structure (just like IPv6!) You can't magically fit 48 bits in a 32 bit field.
IPv6 was the correct long term approach. You wouldn't want to pick only 48 bits and have to do this again in 20 years.
