It hasn't really be done in 5e yet as all Subclasses add something on top of what the Base Class has, but could there be room for Subclasses that take something away from the Base Class to add in something else the Subclass gets in addition to other things? Some Base Classes like Bard don't leave much to work with like only 3 levels where something is gained, so replacing something like magical secrets to get something else might be an example. Or maybe even more drastic where abilities they got before subclasses get replaced with something new in the subclass.
I think in theory these might be more difficult to balance against other subclasses, as a lot of the ideas behind a subclass is that they usually work along side the base class.
